Jennifer Lopez sparks rumours of dating her dancer

Jennifer Lopez has sparked rumours she is romancing a toyboy dancer after she was snapped hugging a hunk during rehearsals for Sunday's American Music Awards.

The Jenny from the Block superstar has been linked to Casper Smart, 24, for several weeks, following her split from singer husband Marc Anthony.

Lopez has refused to confirm of deny reports she is dating her back-up dancer, but she was caught on camera embracing him and staring into his arms during a break from practising their performance in LA on Sunday.

Lopez and Anthony announced their split after seven years of marriage.
