Jennifer Lopez Flaunts Bikini Bod, Teases 'Ain't Your Mama' Music Video

Jennifer Lopez shared a number of gifts with her Instagram followers on Thursday, first flaunting her figure in a steamy bikini photo, and then teasing her new music video with a stylized sneak peek.

Laying out in the spring sun, the former American Idol judge snapped a sexy selfie showing off her white bikini top and aviator sunglasses.

"Happy sunny day!!" the 46-year-old captioned the sultry shot. "Are you guys ready for #aintyourmama video!!??"

Four hours later, Lopez made good on her tease when she shared a sneak peek at the music video for her song "Ain't Your Mama" with a vintage-looking, sepia-toned behind-the-scenes clip.

The video, which premieres Friday on Vevo, appears to feature Lopez dressed up like a 1950s housewife, complete with a voluminous, Stepford Wives-esque 'do.
