Jennifer Lopez and Casper Smart holding hands

Jennifer Lopez has been spotted holding hands with Casper Smart.

The 'On The Floor' hitmaker has previously insisted she is single but she seemed quite smitten with her ex-boyfriend as they walked hand in hand whilst on the set of Jennifer's new police drama, 'Shades of Blue'.

Their public display of affection comes only days after Jennifer admitted she is enjoying having "no one to answer to".

She said previously: "In my twenties, I was so focused on my career and on boyfriends, and now I realise it's about focusing on feeling good about yourself.

"Being single is good. You have no one to answer to, so you can do whatever you want, but I don't go wild or anything."

In recent weeks, Jennifer has been spotted kissing Casper as well as referring to him as her crush on Instagram, fuelling speculation the pair have rekindled their romance.

The 45-year-old beauty - who has seven-year-old twins Max and Emme from a previous relationship - even recently admitted she was "kind of" single.

Speaking on The Ellen DeGeneres show, she said: "I'm kind of not single, but I kind of am."

The pair previously dated in 2011 for three years, splitting up last June.
