Christina Milian and The-Dream celebrated their engagement with a private party in Las Vegas on Friday night.

The “Dip It Low” singer and “Umbrella” songwriter, born Terius Nash, flew their family and friends to the Palms Resort & Casino to toast their upcoming nuptials, reports RadarOnline.com.

The party started at the pool and ended up in one of the hotel’s plush suites, with guests enjoying music into the early morning. The dress code called for casual attire and swimwear.

Ray Kay, who directed several of Christina’s music videos, was among the guests. “I’m at Christina Milian and Dream’s engagement party in Vegas,” he tweeted.

The couple began dating earlier this year. Christina will release her new album Elope on The-Dream’s Radio Killa Records this fall. No wedding date has been announced.
