She recently lifted the lid on her personal life, revealing she kissed Zoe Kravitz and engaged in a ‘toilet sex romp’ with married Liam Gallagher.

And Lily Allen appeared in high spirits as she attended the star-studded 2018 Hyundai Mercury Music Prize at London’s Eventim Apollo on Thursday evening.

The singer, 33, oozed sophistication as she slipped into an elaborate semi-sheer dress, embellished with quirky feathers details throughout.

Lily’s outing comes after she revealed details of her mile-high sex romp with former Oasis frontman Liam, 45, in an excerpt from her tell-all autobiography My Thoughts Exactly on Sunday.

And the singer had another confession to make in her book, as she revealed that she kissed No Reservations actress Zoe, 29, while on tour with her in 2014, when she was still married to Sam Cooper.

Detailing the experience in her book, the 33-year-old explained: ‘For my New York shows, Zoe Kravitz and her band Lolawolf supported me, so I got to know Zoe a bit. We became friends.

‘Later in the tour, when we were in Washington, the girls and their nanny, Jess, came out to visit me for a few days, but I had to go back to New York for a day or so for work.

‘Zoe and I went out partying and ended up kissing. I heard that later that same night she’d got down with A$AP Rocky.’

It was during this tour that Lily admitted to sleeping with female prostitutes following the breakdown of her marriage to Cooper.

‘When we landed in Tokyo, Liam said, in his distinctive nasal twang, ‘What you doing now? Why don’t you come back to our hotel’… I was like, ‘Yeah, OK’.’

However, Liam was married to All Saints singer Nicole Appleton at the time and he begged Lily, who admitted she had ‘grown up an Oasis fan’, never to reveal their fling.

She added: ‘It wasn’t until the next day when he said something like, ‘No one can hear about this because of Nic,’ then I clocked he was married. I knew Noel was married and I knew Liam had been married to Patsy Kensit. That was partly why I fancied him.

Despite hoping the secret romp would never see the light of day, Nicole discovered the truth six months later and Liam asked Lily to lie to his wife.

The Fear songstress explained the hitmaker ‘sounded awful, like he’d been up all night’ when he said he needed her to tell Nicole their night of passion was ‘b*****ks’.

However, Lily fired back at the Beady Eye rocker and blasted him for his actions, insisting that he was only trying to save face ‘and not disrupt what really matters: The people we love and rely on.’ 

MailOnline have contacted Liam Gallagher’s representative for comment.
