Christina Milian and The Dream kept their engagement a secret and their sudden Las Vegas nuptials under wraps, but now they're ready to share their big day with family and friends.

According to a source, Milian and her singer-producer husband (real name: Terius Hagert Youngdell Nash), both 27, are planning another wedding to include everyone who missed the elopement. The couple even stopped into Sunset Plaza's Buttercake Bakery in LA last week for a private wedding cake tasting.

Their favorite? Vanilla. And they were looking at three-layer cake. "They seemed so happy," says a source. "They were so sweet and looked so in love."

The date of the ceremony wasn't known. A rep for Milian couldn't be reached for comment.
