Summer Monteys-Fullam may have been caught up in one of the messiest celebrity divorces of the last few years, but she's not letting it getting her down.

The 24-year-old proved she was still living her best life when she shared a cheeky beflie on Instagram on Tuesday night.

She flashed her cleavage and showed off her peachy bottom as she lay on her front on a bed in the saucy phot.

Summer, who is the ex of Paul Hollywood, donned a thong swimsuit and a pair of killer sparkly heels as she posed with her legs crossed in the air behind her.

She poked out her tongue and had a huge grin on her face as she posed for the camera.

Her trademark red hair was worn in loose curls around her shoulders and she donned a big pair of hoop earrings.

Summer showed off her sass as she flicked her hair over the shoulder and stared down the lens.

In the caption she said she was practising "self love" in defiance of her haters.

She wrote: "Self love is the greatest middle finger of all time."

It comes after Paul's ex wife Alex said it was "her time to shine" after their "horrendous" divorce.

The couple split in 2017 after Paul was unfaithful for a second time, this time having a fling with barmaid Summer.

Summer and Paul broke up last year when she refused to sign a non-disclosure agreement that meant she couldn't discuss their relationship.

Paul previously had an affair with Marcela Valladolid but Alex gave him another chance at the time.

She told OK! this week: "Through hard graft from both of us, he got to the point where he was so big with Bake Off and now it's my time to shine.

"I'm not saying I don't wish him well, I really hope that he will find happiness."
