Jamie Lynn Spears attends the show of sister Britney's rival Christina Aguilera - as the Dirrty singer closes out her Las Vegas residency

Jamie Lynn Spears caught the final show of Christina Aguilera’s Las Vegas residency on Saturday night.

Jamie’s sister Britney Spears and Christina have a long and complicated history together, as the former Mickey Mouse Club stars began their careers alongside each other in the early 1990s and soared to fame while constantly being pitted against one another.

The actress, 32, who is estranged from her only sister, looked gorgeous in a black dress as she watched the Grammy winner rock the audience.

Her long, blonde hair was styled in loose waves and held away from her face with a hairpin.

The Zoey 102 star was on her phone and standing next to a woman wearing a ‘Bride to be’ sash, in the video shared on X by the @britneychart fan account,  but it was unclear if she was there as part of a bachelorette party.
