Rumors are percolating that Lil Wayne and Christina Milian could be back together after the former couple recently engaged in an explicit bump and grind session on the Miami set of their new "Do It" music video.

E! Online reports, with Milian wearing "an incredibly sexy and barely there outfit," the two got closer and closer in the video as wagging tongues looked on. Just last month, the pair cited their busy and conflicting schedules as one of the primary reasons behind their split.

"They have broken up," a source said back then. "Their schedules started getting extremely busy and the distance was not easy for them both."

The source later added the two were just taking a break and did not part on bad terms. That much seemed pretty obvious from the video, in which Milian rubs her booty against her ex as they are surrounded by a bevy equally, skimpily dressed female dancers.

The two first began publicly dating back in July 2014, and soon after that Milian was raving about how captivating her new man was.

"I guess I just like the mystery," she said of keeping their union under wraps for a while. "I think it's so sexy. I like to keep the sexiness going."

In time, Milian got a sexy new tattoo that read "love hard," which she admitted was inspired by her boyfriend.

"You can make your special guesses ... of what that means," she said. "We have a very fun and cool relationship. There are so many things, what do I start with? He's very genuine. He's a very genuine person and no matter what, love comes first with him."

Season 2 of Milian's "Christina Milian Turned Up" series premieres early next month on the E! Network.
