The singer wore a little minidress with a blue skirt and a diamanté top half.

The neckline plummeted, highlighting the star’s assets as she danced in the video.

She shimmied and twirled for the camera, fiddling with her hair and top.

“Mexico,” she captioned the photo, with a flag emoji and multiple faces.

Britney’s long blonde hair was hanging about her face, and she wore red lipstick and underliner for a glamorous look.

She accessorized with a pair of high-heeled black heels, which added height to the appearance.

Fans clearly liked the video, as it received over 200 thousand likes, but the star disabled the comments.

This follows allegations that Britney and her husband Sam Asghari’s relationship took a drastic turn less than a year after they married.

When they were both seen without their wedding rings last month, rumors of marital problems began to circulate.

Britney then made a recent Instagram comment about partnerships, which some fans believe alludes to her own marriage.

She disclosed: “In every relationship, there’s the person who falls asleep instantly and the other person who lies awake wondering how that’s even possible.”

However, according to sources, the couple’s relationship is OK: “All is good. Sam is working on a project, and she is on vacation with [manager] Cade [Hudson].”
