Christina Milian's longtime music video director Ray Kay has confirmed the star is to wed R&B singer/producer The-Dream - after blogging about attending the couple's engagement party in Las Vegas on Friday.

Milian, who has been romantically linked to the Umbrella songwriter since February, sparked rumors she was heading down the aisle with The-Dream after she was recently spotted wearing a diamond ring on her wedding finger. The singer/actress dismissed the claims, insisting rumors she was engaged were "pretty funny."

However, Kay appears to have let slip the stars' happy news after joining the couple's friends and family at the Palms Resort & Casino to toast their impending nuptials.

Writing on social networking site Twitter.com on Friday, he said, "I'm at Christina Milian and Dream's engagement party in Vegas."

Milian has previously dated Mariah Carey's husband Nick Cannon, while The-Dream's marriage to singer Nivea, with whom he has three young children, ended in late 2007.
