, said: “Brianne’s engagement ring looks to be a 3-carat pear shaped diamond with a diamond halo. Assuming it is a white diamond with a colour clarity of G VS, the ring would retail for around £53,000.”
The pair were eliminated from the competition on Sunday night and shared a steamy snog following their skate off performance, leaving host Holly Willoughby blushing.
The whirlwind romance only began when they partnered up on the show late last year, and they recently moved in together.
The Sun Online exclusively revealed the ITV show stars were dating in December.
The loved-up couple recently spoke out about their living arrangements to Mirror Online in a candid chat in which they discussed their household task sharing.
Kevin said: “I’m certainly not the boss on the ice. Bri holds me up all the time, she controls it.”
Brianne added: “He takes more control at home. He cooks the meals, does the laundry. He’s more of the boss.”
“Home life is completely separate. We do what we have to do on the ice, then we go home and it’s back to family life."
The skater has a daughter Gracie, aged three, who is more than happy with the new arrangement.
Brianne added: "We are really happy. Gracie adores Kevin. It’s very comfortable."
The pro skater has also dated Corrie’s Danny Young and EastEnders actors Sam Attwater and Matt Lapinskas.
Canadian Brianne partnered with Matt on the show in 2013 but they split amid accusations he cheated on her with two other women.
Kevin won 110 caps for Ireland and played for nine clubs including Everton and Sunderland.
He is single after splitting from wife Laura in 2011.
A source said: “There was a real attraction and chemistry between the two of them from the word go.
