Tom Selleck, 69, gets hearts a fluttering as he films Blue Bloods in New York

He was one of America's hottest heartthrobs when he starred as a rugged former Navy SEAL in Magnum PI.

And Tom Selleck was looking as handsome as ever he filmed scenes for his TV show Blue Bloods in New York on Wednesday.

It seems romance may be in the air for his Police Commissioner character Frank Reagan, as he was escorting former Cheers favourite Bebe Neuwirth down the street as the cameras rolled.

I moustache you a question: Bebe Neuwirth looked like she was about to pose a query to Tom Selleck as they filmed Blue Bloods in New York on Wednesday

Tom was looking good for his age in a suit, raincoat and smart leather shoes, before changing into a more casual outfit later in the day.

Perhaps most excitingly, his famous moustache was looking as gloriously bushy as ever as he took part in the day's shoot.

His companion Bebe, 55, plays Kelly Peterson, the stylish and charming Inspector General overseeing Frank’s department.

While her fiery character is not afraid to butt heads with the widowed police chief, sparks are said to have flown between the pair in their pre-show past.

No doubt Bebe finds the Mr Baseball star easier on the eye than her former on-screen husband, Frasier star Kelsey Grammer.

Selleck stars in the show alongside New Kids On The Block legend Donnie Wahlberg, Bridget Moynahan, Len Cariou and Will Estes.

They make up the Irish-American Reagan family who are all officers in the New York City Police Department.

Tom first came to prominence for his role as private investigator Thomas Magnum in hit 80s series Magnum PI, which won his fabulous moustache a small army of fans, while also being memorable for his character's penchant for wearing loud Aloha shirts.
