Christina Milian stuns in a zip-up swimsuit in Las Vegas (Photos)

Christina Milian took the plunge in a zip-up swimsuit while hosting her poolside bash at the Flamingo Las Vegas Hotel & Casino on Saturday.

The Emmy winner – who turns 34 next month – had a blast chilling with her BFF/assistant Lauren Rodgers and make-up artist Angel Merino. The reality star couldn’t overdo it either as she’s also hosting Champagne Sundays at the the LINQ Hotel & Casino the very next day. More photos below…
