Shanna Moakler goes casual in sweats as she buys underwear at Target in Los Angeles

Her ex-husband Travis Barker has been living a life of luxury while vacationing in Italy for his third marriage ceremony with his new wife Kourtney Kardashian.

But Shanna Moakler was back home in Los Angeles on Sunday while her ex and children were abroad celebrating.

The 47-year-old model was spotted rocking a casual sporty look while stopping by a Target to shop for some underwear.

Shanna looked relaxed in a black hoodie decorated with a black-and-white Tiger head, along with stars and stripes.

She paired it with a matching set of sweatpants with the same design, which she rolled up to showcase her toned legs.

The blond beauty contrasted her dark ensemble with brilliant white trainers, and she styled her hair back in a  high ponytail.

She blocked out the sun with a cool set of aviator sunglasses.

Then she dropped by a Target location, where she was pictured perusing a bra display.

Shanna’s outing comes after some of her fans thought she alluded to her ex-husband Travis’ Italian wedding on her Instagram account.

On Friday, she posted a closeup photo of herself and captioned it, ‘I have no energy for hate. I either love you, wish you well or hope you heal,’ adding the hashtags, ‘#godspeed’ and ‘#namaste.’

Several fans in the comments were convinced that she was referring to Travis, who was spending time in Portofino ahead of his nuptials with Kourtney.

The day before, she had posted another cryptic message to her Instagram Stories.

‘My arguing days are over.. enjoy your day baby,’ she wrote, though it wasn’t clear if it was addressed to her ex or a family member.

On Sunday, Travis and his new bride Kourtney were seen celebrating their big day by taking a plunge off the side of the luxury yacht they have been spending time on in recent days.

Shanna’s children whom she shares with Travis have been a sore subject throughout his relationship with Kourtney, as his ex has accused the relationship of coming between her and the kids.

Their son Landon, 18, and daughter Alabama, 16, joined in on the Italian trip, as did Shanna’s daughter Atiana De La Hoya, 23, from her relationship with boxer Oscar De La Hoya.

Travis raised her as one of his own during their marriage, and she has maintained strong ties with him even after he divorced her mother in 2008.

Although Alabama and Shanna were vocal about their estrangement early on in Travis and Kourtney’s relationship, they’ve since signaled a thaw in their relationship.

Earlier in May, Shanna even excitedly promoted Alabama’s new PrettyLittleThing campaign on her Instagram account.
