Christina Milian reunites with her ex-boyfriend, Lil Wayne, in the steamy visual for "Do It."

The video starts with Milian and her girlfriends heading down the road in an expensive car. But soon their ride is heading in reverse -- not to be daredevils -- but because they're heading back in time to six hours prior.

Milian is sitting on her bed when she gets a text from Wayne, asking her if she's heading out. The "Dip it Low" singer begins rolling around on her white linen sheets in a Calvin Klein sports bra and boy shorts. "Usually a virtuous woman / Now we don't even know what we doing / But I'mma go ahead and do it," she sings.

The Stephen Garnett-directed video continues to follow Milian to a graffiti-filled skatepark where she meets up with Weezy. And as he delivers a few bars, Milian cozies up to him and even grinds on him a few times.

While their steamy scenes together make for good visuals in front of the camera, it seems there's trouble brewing for the two in real life. The "Say I" songstress tweeted some harsh words on Thanksgiving last week.

“Stop telling me that you love me,” she wrote in the now deleted tweet. “Stop asking me to come see you. I’m definitely not interested. #BeenOverIt #HappyNoThanksGiving #Single.” Ouch.

"Do It" is off of Milian's forthcoming EP, 4U, which is set to be released on Friday (Dec. 4). It will include four tracks along with accompanying music videos.
