Jennifer Lopez suggested that she's "kind of" single recently, but after being spotted on the set of her upcoming police drama walking hand-in-hand with Casper Smart on Thursday (4 June), her actions tell a different story.

Despite avoiding addressing her relationship with on-again-off-again boyfriend Smart on The Ellen Show last month by coyly saying "I'm kind of not single, but I kind of am," the 45-year-old seemed pretty loved-up with him as she filmed her new show Shades Of Blue in New York yesterday.

Lopez and Smart were confirmed to be dating back in 2011, when the former American Idol judge split from her husband of ten years, Marc Anthony, and were together for almost three years before breaking up in June of last year.

But since late last year, the pair have been seen spending time together frequently again; going out to dinner, holidaying with Lopez's children and even accompanying one another to public industry events; the latest of which was the 2015 Billboard Music Awards in May.

Early last month, Lopez posted a photograph of Smart on her personal Instagram account, alongside the caption "#MCM @beaucaspersmart #lovethispic #HandsomeBear," which fuelled the rumours that they were a couple even further.

But the twosome have yet to officially announce they are an item, the Booty singer even dismissing the idea that they are romantically involved by stating recently that herself and the 28-year-old choreographer are just "very good friends" despite having "ties" and being "very close".

Lopez's new show, Shades Of Blue, which also sees her act as executive producer, has her playing Brooklyn-based Detective Harlee McCord across a 13-episode long first season, co-starring Ray Liotta and Son Of Anarchy's Drea De Matteo.

In the programme, McCord is recruited to work undercover as part of an internal anti-corruption task force within the FBI which proves to be a morally-difficult job, especially as she has to juggle the responsibilities of motherhood alongside her duties. The drama will air sometime later this year on NBC.
