Look away Casper! Jennifer Lopez smiles then hugs hunky mystery man on set of Shades Of Blue as beau Mr Smart is absent 

She has seemed to have eyes only for Casper Smart, 28, this year as their relationship has gone from done to hot all over again.

But on Friday Jennifer Lopez was showering her attention on another hunky guy while taking a break from shooting her new cop series Shades Of Blue in New York City.

The 45-year-old actress was seen smiling at then hugging a ruggedly handsome mystery man as the I Luh Ya Papi singer's sister Lynda, 44, looked on.

When J-Lo first laid eyes on the twentysomething man, who was over six feet tall and had on a fitted blue T-shirt that showed off hit toned torso, she lit up.

It didn't take long before the Booty hit maker flashed that Vogue cover girl smile.

Within seconds the American Idol judge had both arms wrapped around the fellow with her chin resting on his sculpted shoulder.

The Bronx native was dressed in her costume to play Harlee McCord, a single mom works undercover for the FBI on an anti-corruption task force unit.

She is also producing the show along with her company Nuyorican Productions.

The Glow perfume mogul had on a white button-down shirt that was tucked into a pair of tailored black slacks.

The mother to twins Max and Emme also had a holstered gun on her belt as well as a NYPD badge.

The beauty - who turns age 46 on July 24 - appeared youthful with her famous locks cut short into a wavy bob.

She recently said that she had cut her hair, but the length seems to be the same as it was in June.

The On The 6 crooner also had on just enough makeup to look pretty but not overly done up like a star.

It is not known who the mystery man is or how he knows Jennifer, but he could have been a friend of her sister Lynda who was also on set.

Where did the glow go? Lopez was also seen with her co-star Ray Liotta on set, but when with him, her attitude was not the same

It was not clear if the two were just passing time during a break or were really shooting a scene together.

Jennifer's on-again beau Casper Smart has not been seen on set of her new NBC series since early June.

The two made their reunion public around the time of the Grammy Awards in the winter.

The couple split in June 2014 after allegations the backup dancer had spent time with a transsexual, which he denied.

Also on Friday the Jenny From The Block singer shared a photo where she was embracing best friend Leah Remini. Her caption read, 'Reunited and it feels soooo good!!'
