The Ex On The Beach star showed off her sizeable assets as she went braless in a sexy new shot.
The 28-year-old, who is currently dating Stephe Bear, was seen in the snap wearing an open blue jacket and she held her dog.
However, despite showing off her body, the star was actually promoting her bracelet.
Jem captioned the picture: "Always got my @infinitybraceletuk on! This new diamond anchor detail is so cute get yours."
However, her followers seemed more interested in her cleavage than her jewellery.
One wrote: "Coz everybody is clearly looking at the bracelet and it's cute detail! [sic]."
Another added: "Always got your bra off."
While a third said: "Your boobs are literally quadruple the size of your dog's head man."
However, the picture should come as a surprise to fan, as Jem's known for her racy shots.
The snap followers Jem's outlandish comments on d*** pics last week.
The star told Daily Star Online: "I get DM's all day long but they are either from ugly people… or just people who want to use me," she ranted.
