Kristina Rihanoff has given fans the first glimpse of her growing baby bump. The former Strictly Come Dancing star, who is expecting her first child with boyfriend Ben Cohen, has proudly retweeted a picture on Twitter.

The mum-to-be and her fellow dancer Katya Virshilas, who also starred on Strictly, are seen comparing bump sizes, with Kristina showing off a sizeable bump at four months pregnant.

"Lovely catch up with mama to be @KRihanoff #16weeks and me #25weeks pregnant!" wrote Katya alongside the photo.

The pair will have had a lot to talk about, swapping stories about their pregnancy experiences. Both Kristina and Katya are set to become first-time mothers this year, although Katya, who is married to ballroom dancer Klaus Kongsdal, sadly suffered a miscarriage in 2014.

Katya's baby is due in May, while Kristina is expecting a summer birth.

Speaking about her surprise pregnancy, Kristina told HELLO! exclusively: "It was a surprise but I am obviously delighted. My mother was with me over Christmas and when we found out she put her arms around me and she cried with joy. It is her lifelong dream for me to have a child and it was lovely to see her so happy."

After eight years Kristina also closed the door on her Strictly days, leaving her to focus on her and Ben's unborn child.

"It's a bittersweet situation," she said, before adding: "I think I am on a new path, learning about myself, how to relax and how to enjoy a more simple and balanced life. I can't say I'm not nervous. But I'm very excited about the future."

Just last week Kristina showed fans just a hint of her bump, as she was reunited with her fellow Celebrity Big Brother housemates for the show's finale. Stepping out in a midnight blue gown that featured an empire waistline, Kristina had that pregnancy glow about her on the glitzy night out.
