Jessie J embarrassed by Arquette crush questions

Jessie J has opened up about the "most awkward" moment of her life.

The singer was left embarrassed when Courteney Cox was questioned about her estranged husband David Arquette's crush on the Domino star.

Jessie was backstage at Jay Leno's talk show when he asked Courteney how she felt about David's adoration.

"It was probably the most awkward moment of my life. But she was cool about it," she told Australian radio's The Kyle and Jackie O Show.

"I was backstage watching it on TV so everyone was looking at me."

The 24-year-old star is happily single and has no time for relationships. With her work as a mentor on the UK version of talent show The Voice and her album Who You Are topping the music charts, Jessie has her plate full.

"Do you know what, my music is what I love at the moment so David Arquette can fancy me all he likes but I'm focused on that," she laughed

Jessie started out behind the scenes writing hits for the likes of Chris Brown and Miley Cyrus. The spotlight is now on her with the release of her own popular tracks.

"I kind of always wanted to be an artist myself and in the beginning I think I was better off going into the studio and not having boundaries in what I wrote about and at the time there were other artists that needed the songs or suited the songs more than I did," she said.

"And if I wasn't ready to come out it felt kind of silly to not give Miley Cyrus or Chris Brown the songs."
