Lottie Moss holds the hand of her new rockstar boyfriend Tristan Evans

It was revealed last week that her new boyfriend is Vamps drummer Tristan Evans.

And Lottie Moss and Tristan, 26, put on a warm show when they made their first public appearance as a couple on Wednesday, stepping out in London to attend a glitzy launch party.

Lottie, 23, looked distinctively fabulous in an off-the-shoulder patterned dress that showed off her impeccable figure, and the blonde beauty made sure to hold her new beau’s hand as they made their way to the venue top of the line.

Once inside, Tristan quickly wrapped his arm around his model girlfriend as they posed for the photographers, with the 6-foot-1 musician towering over Lottie, despite wearing heels.

Showcasing his rocker credentials, Tristan paired a leather jacket with bright red pants and completed his look with waxed boots while making sure all eyes were on his purple tinted hair.

Actress Isabella Charlotta Poppius also stepped out mid-week, pairing a thigh-low white miniskirt with a matching jacket and chic black tee.

Elsewhere, photographer Alistair Guy made sure to turn heads in a bright purple suit and actor Jack Brett looked dapper in an off-white t-shirt and beige jeans.

Film star Mark Ebulué gave attendees a lesson in sophisticated style, layering a black shirt under a navy suit and posing for photos with actress Maria Jose Bavio, who paired a black dress with red heels breathtaking.

It was revealed in late July that Lottie and Tristan were an object, after they were spotted getting closer in Notting Hill last week before spending the next evening cooking for her on a comfortable night out together.

The couple kissed passionately on the street as they shared a cigarette after leaving a romantic dinner at the modern European restaurant Gold.

Bolder than her usual type, Lottie once dated Made In Chelsea boys Alex Mytton, 30, and Sam Prince, 24.

Meanwhile, Tristan got engaged to model Anastasia Smith in April 2018, after dating for four years, but in the fall the couple broke up, removing all photos together from their social media profiles. Anastasia is now engaged to another man.

Last November, the Vamps drummer told Attitude that “there should be no limits” when it comes to sex.

Around the same time, Lottie got into pansexuality.

Kate Moss’s younger stepsister told her Instagram followers, “I’m pansexual so I don’t really mind… any gender.

“It changes a little every day too. It depends on who I meet.

A pansexual person is attracted to or falls in love with someone, regardless of their biological sex or gender identity.
