Jennifer Lopez and Casper Smart were spotted out and about together during Grammy weekend, further fueling growing speculation the former high-profile couple might be on the rebound.

TMZ reports the "If You Had My Love" singer and Smart spent Saturday night at Big Sean's Roc Nation bash "shakin their booties and having a blast." The website adds the couple were out with Demi Lovato and Wilmer Valderrama.

The sighting comes just days after the pair were seen together in Los Angeles and almost eight months after they publicly announced their split. TMZ adds Smart attended an event hosted by Nick Jonas on Thursday, returning to his car after the event to find Lopez waiting for him.

The New York Daily News also reports the pair were seen that night at Hollywood's Hotel Café and as they walked pass photographers Smart had his hand on Lopez's waist.

The 45-year-old Lopez and the 27-year-old Smart previously dated for nearly three years. As far back as August, Lopez was seen riding with Smart in his convertible, quickly sliding down in her seat to hide as they approached paparazzi. Days later, Smart stopped by Lopez's seat at the MTV VMA's to share his Skittles with her.

"You get to a point in your life where it's not anybody else when things work out or don't work out," Lopez recently told reporters while promoting her movie "The Boy Next Door," the plot of wich centers around her becoming romantically involved with a younger man.

"I think that's been a big part of my journey to finally sit back and go, 'Hey what is it that you think you're doing?'"

The three-times divorced Lopez has also previously been romatically linked to Ben Affleck, Sean "Diddy" Combs and Marc Anthony, the father of her six-year-old twin children, Max and Emme.
