Photos: Christina Milian Hits Miami Beach in Red Bikini with Major Underboob

Christina Milian flaunted it Saturday in Miami Beach, and we took proper notice.

The singer was wearing a hot red top with a cut that certainly accentuates her underboob.
Christina was having fun in the son with her baby nephew Lavvin.

Christina and Karrueche Tran have been hanging out recently, and it's a shame Chris Brown's ex didn't choose to accompany her best bud to the ocean blue. Not that we're complaining, but what a pair they make.
