Christina Milian threw her boyfriend Lil Wayne a surprise birthday party last week.

However, the surprises didn't stop there as the brunette beauty also treated Lil Wayne - whose real name is Dwayne Michael Carter, Jr. - to a custom-made white chocolate cake, which had been made in the shape of a skateboard and decorated by Platinum Event Decor.

Although, it appears most of the calorific treat ended up on the floor as the party broke out into a food fight.

Taking to her Twitter account the day after (25.09.14), Christina

wrote: "Cake Fights Allllll Night.. Too much fun.. Happy Early Bday Boss :) @LilTunechi #CakeDay Part 2 Best Time Ever (sic)."

Meanwhile, the couple first sparked speculation they were dating after they were pictured holding hands at the beginning of July and then again looking very cosy at the 2014 ESPY Awards in Los Angeles on July 16.

A source said at the time: "It is totally true. They are hooking up."

However, the rumours came as a shock to fans as Christina only split up with her fiancé Jas Prince just over a month before.

Christina also has a daughter, four-year-old Violet, with her ex-husband The Dream, whom she married in 2009 before splitting just two years later.

Wayne was previously married to Antonia Wright between 2004 and 2006, with whom he has a daughter, Reginae, and he also has three other children who were all born to different mothers.
