Los Angeles, Feb 10 (IANS): Singer-actress Jennifer Lopez has fuelled reconciliation rumours with her former boyfriend Casper Smart after the duo was spotted together at rapper Big Sean's concert

In a video, Lopez is seen enjoying Kanye West and Sean's performance while standing next to Smart at the balcony of a restaurant, reports aceshowbiz.com.

Lopez, 45, and the 27-year-old dancer and choreographer are seen enjoying the music while dancing together. At one moment, West is seen shouting out Lopez's name while rapping onstage.

After the show, Lopez shared on Instagram some photographs of her with other celebrities, but not with Smart.

The “On the Floor” hitmaker posed for a group image with West, Sean, Chris Brown, Justin Bieber and Kendall Jenner. She also took a photograph with Demi Lovato.

Lopez first sparked reconciliation rumours with Smart after they were spotted together outside the Hotel Cafe here last week. At that time, Smart was seen wrapping his hand around Lopez's waist.
