Singer Jessie J has sent fans into overdrive with her latest steamy offering.
The Do It Like A Dude singer posted a mirror snap to her Instagram stories in which she hides her face, but is clearly without clothes aside from a pair of Calvin Klein underwear.
"Not an ad!" the 31 year old hit maker wrote, "But I am...#inmycalvins."
Jessie rocketed to fame back in 2011 with a string of hits including Price Tag and Do It Like A Dude, with her music career going from strength to strength since.
She now boasts collaborations with other global mega stars like Ariana Grande , Nicki Minaj and Big Sean, and has drawn even more attention recently because of her relationship with Hollywood heart throb Channing Tatum .


They've been one of showbiz's hottest couples for nearly a year now, and have even shacked up together in a mansion near Bury St Edmunds.
Jessie spoke to The Times after the first time she'd met Channing's six year old daughter, Everly.

"She's just six and absolutely lovely," said Jessie.
Jessie added of her blossoming relationship: "Chan and I got photographed before our relationship was even a thing and that created such pressure.
"We've needed to get to know each other. We've just had our first holiday together, which was wonderful, but that's all I'm saying..."
They first found a spark in the months following the breakdown of Channing's marriage to ex-wife and mother of Everly, Jenna Dewan.
The pair announced their split in April last year, with Jenna admitting she "felt blindsided" when she found out Channing was romancing the singer.
