Megan was ready to paint the town red wearing a bright red bra with a matching coat hemmed just below her hips.

Peeks of her abdominal tattoo peered out as she sported a pair of high-waisted trousers to match.

Sticking with her monochrome ensemble, Megan added inches to her petite frame with a pair of platform pumps.

The Teenage Mutant Ninja Turtles star swiped a matching shade across her lips and showed off expert cat-eye black eyeliner.

MGK wore a blue mock-neck sweater with bright red stripes to coordinate with his leading lady.

Megan and Kelly went public with their new relationship in May 2020 after meeting on the set of Randall Emmett’s directorial debut, Midnight In The Switchgrass.

The Transformers star ‘is definitely in love’ with her beau, but is ‘having a great time with where things are at now,’ the source said.

She filed for divorce from her husband of 10-years, Brian Austin Green, on the day before Thanksgiving, and the couple are currently trying to figure out a custody arrangement for their three children.

‘She really takes her kids into consideration and knows that taking that next step would be a big adjustment, but it’s not off the table,’ the insider added.

‘There is definitely still some tension between Brian and Megan as they had a difficult separation, but they manage to make it work for the sake of the kids.’

Kelly — who’s real name is Richard Colson Baker — has a 12-year-old daughter from a previous relationship named Casie.

They made their red carpet debut at the American Music Awards where she revealed a new tattoo likely dedicated to her musician beau with the Spanish words ‘el pistolero’ scrawled across her collarbone, which roughly translates to ‘the gunman.’

During an interview on Lala Kent’s podcast, Megan said she ‘knew right away that he was what I call a twin flame.’

She added: ‘Instead of a soul mate, a twin flame is actually where a soul has ascended into a high enough level that it can be split into two different bodies at the same time. So we’re actually two halves of the same soul, I think.’
