Christina Milian showed there must be good genes in her family last night, when she stepped out with her sister.

The Voice host treated her younger sister to a night out at Bardot in Hollywood, where other members of the show partied including Cee-Lo Green.

Christina looked stunning as always wearing a blue-patterned dress that clung to her curves, while her sister - either Elizabeth or Danielle - opted for a more glamorous look, wearing a black dress with a see-through cut-out panel on her chest area.

Both ladies are clearly beautiful, but who looked best last night?
