Christina Aguilera is showing peeks at Selena Gomez’s 31st birthday party, which was full of famous people.

Aguilera, who is 42, took pictures with Selena and Karol G at the Wizards of Waverly Place star’s 31st birthday party.

“Love these girls,” the Genie in a Bottle singer wrote in the post’s caption, which included pictures of her posing with the Ice Cream singer and the Don’t Be Shy trap artist.

The blonde beauty looked comfortable in a long floral dress and a long denim jacket, while Selena showed off her toned legs in a stringy red minidress.

At the same time, Karol wore a blush pink Barbiecore dress and a pair of black sunglasses to match Christina’s relaxed attitude.

The birthday girl wore her dark hair in an elegant bun, while Christina let her long, silver hair hang loose around her shoulders. The Provenza singer went for a cool ponytail and let her blonde hair hang loose around her face. In one picture, she stuck her tongue out with the Dirrty singer.

Even though the three A-list musicians haven’t said yes or no to a possible musical collaboration, two of the singers haven’t put out a full-length studio album in more than a year.
