Tristan Thompson was seen disappearing into a bedroom with three women at a Bel Air party

Tristan Thompson disappeared into a bedroom with three women during a Bel Air birthday party – and emerged ‘disheveled’ 30 minutes later, DailyMail.com can reveal.

The Boston Celtics star’s antics came on Friday night – less than 24 hours after he was photographed with on-off girlfriend Khloe Kardashian and their daughter True, three, for the first time in two months.

Sources exclusively told DailyMail.com that Thompson, 30, headed straight for the bar after arriving at the party just after midnight and did a round of ultra-luxurious Deleon tequila shots while swigging Moet champagne before repeatedly grabbing the bottom of a female guest. 

Two hours later, he was seen making his way to a bedroom in the Bel Air mansion where the party was held accompanied by three women and a male friend.

Thompson emerged from the room 30 minutes later with his dark red shirt crumpled and looking ‘a mess’ and returned to the bar.

‘He immediately beelined to the bar where there were tons of girls; we could hear him yelling let’s do shots!

‘He was having a blast – he was actually laughing and simultaneously taking shots and drinking straight out of a bottle of champagne.

‘He was repeatedly grabbing this one girl’s butt so we all knew he was totally into her.’

'The house was so big that you could get lost in it. You had to take an elevator to each floor and the LED lights were all blue throughout the party,' one guest said

Later, Thompson disappeared into a bedroom with the same girl and two of her friends and didn’t come out for half an hour.

The insider said: ‘A couple of hours later, Tristan took off into one of the party rooms where everyone goes to hook up.

The Boston Celtics star's antics came on Friday night – less than 24 hours after he was photographed with on-off girlfriend Khloe Kardashian and their daughter True, three, for the first time in two months

‘He was with three women and another guy. One of the girls he was with is a regular partier – she always out and about at parties.

‘The other girls have just started going out with this group. He did this in front of about 30 people so you could hear people talking.

‘They stayed in the room behind closed doors for at least 30 minutes. When he arrived, his shirt looked all pressed and when he came out his shirt was a mess, he looked disheveled.

‘He continued to party for about another hour and then he left the party at about 4am with his entourage.’

The source added: ‘In these circles, Tristan is known for partying. He loves to do shots and smoke joints and laugh and flirt with all the girls.

‘He has a reputation for hooking up so when we saw him walk with these three girls and go into the bedroom it wasn’t a surprise.

‘We all were talking about how badly we felt for Khloe and how he was going to embarrass her again.

‘This party was definitely one that he could have invited his girlfriend to – lots of couples came.’

Just hours after DailyMail.com broke the news of Tristan’s actions at the party, Page Six reported that he and Khloe broke up a few weeks ago. 

‘They’re getting along. There is no drama,’ a source said. ‘Everything is amicable and they are on the same page with co-parenting.’ 

Exclusive DailyMail.com video shows the father-of-two at the party, mingling with the mostly female guests while swigging from a cup.

Thompson is wearing the same red shirt that he is seen sporting in a photo posted to his own Instagram account that shows him with Beezer at the party.

The source described how access to the party was tightly controlled, with organizers vetting guests beforehand and shuttling women in from a meeting point down the street.

Guests were handed blue wristbands to get them in, while a select few were given gray wristbands that allowed them into ‘the more exclusive sections’ of the party and access to a dedicated weed bar.

The source added: ‘People were getting pre-rolled joints at the weed bar and others were passing around E’s [ecstasy] and Mollys [MDMA].

‘The house was so big that you could get lost in it. You had to take an elevator to each floor and the LED lights were all blue throughout the party.

‘There were lots of open bars, the drinks were flowing inside and out and there were celebrities in every corner.

‘Tons of models, social influencers, basketball players, Chris Brown, Drake and their entourages were all there. It was a Hollywood scene.’

Khloe Kardashian recently said she rebuilt trust with Tristan after seeing how hard he fought to get back with her.

The 36-year-old answered some tough questions about her relationship with the serial cheater during the second part of the Keeping Up With The Kardashians reunion on Sunday.

Asked if she trusts Tristan, Khloe told host Andy Cohen: ‘I mean, I definitely trust him as a friend and all those things… What I need to find out, everything comes my way. I just need to trust and focus on today and go day by day. I can’t worry too much about everything else. 

‘I know the growth and the work that he’s done. I know all the help that he’s got, and the constant efforts that he makes every single day, and how hard he fought to get back with me currently. I don’t understand why someone would go through all that if they weren’t really serious,’ she said.  

Tristan was caught in new cheating storms as multiple women once again came forward with allegations he had been unfaithful to Khloe, most recently with Kimberly Alexander and model Sydney Chase (pictured)

Thompson’s latest indiscretion comes less than two months after he was accused of cheating on Khloe, 36, by Instagram model Sydney Chase. He has denied her claims.

The 30-year-old has been repeatedly accused of dabbling with other women during his five-year relationship with Khloe, including a 2018 dalliance when the youngest Kardashian sister was nine months pregnant with daughter True.

DailyMail.com photos showed Thompson canoodling with a woman in a New York bar before they back to his hotel room at 5am.

The following year, he was caught kissing Kylie Jenner’s best friend Jordyn Woods during a Valentine’s Day party in LA.

The couple, who have broken up several times, rekindled their romance during the Covid lockdown last year.

DailyMail.com has reached out to representatives for Tristan and Khloe for comment.
