But one canny photographer carried on snapping and the reason for Nick not wanting any more photos being taken became clear - his co-star Samantha Barks was sitting in the back seat.
Nick and Samantha have been spotted out together on a number of occasions since he started his stint in the show on June 22.
Warning: A date with Nick Jonas may lead to nausea and high pitched screaming!
And last night’s show also saw JLS’ Aston Merrygold, Marvin Humes and his girlfriend Rochelle Wiseman from The Saturdays in the audience.
Samantha is the latest of a string of beauties that Nick has wooed while in the UK and just last week was enjoying the company of another Les Miserables co-star - Lucie Jones.
Born and raised on the tiny Isle of Man, Samantha says growing up fame just wasn't a career choice.
"No, I danced because I wanted to dance, I sang because I wanted to sing. It always has." That passion saw the youngster try her hand at everything from ballet, tap, jazz and modern dance to the clarinet and drums. - Aged 16, she convinced her parents to let her move to London to seek fame and fortune.
Nick Jonas seems to be making the most of his time in London while performing in Les Miserables and has been spotted out with yet another one of his female co-stars.
After leaving the Queen’s Theatre in the West End last night, the youngest Jonas brother sneaked into a car with Samantha Barks but tried to hide from paparazzi behind the car seat.
Less than a year later she was well on her way when she took part in , her big break came.
On January 31, 2012, producer Cameron Mackintosh showed up in the audience in Manchester and went onstage during the final curtain to announce that Samantha would play Eponine in his film.
Earlier this month they were snapped leaving the show together as Nick kept his head down to hide from the photographers waiting outside.
