Christina Milian bumps and grinds with 'ex' beau Lil Wayne on set of Do It music video

She was said to have called an end to their love affair. But that did not stop Christina Milian grinding into her supposed ex beau Lil Wayne with aplomb on the set of their music video for collaboration single Do It in Miami. The 34-year-old looked like she was having a great time as she rammed her rear into his crotch as they recorded steamy scenes for the forthcoming promo reel.
