Rachel Riley separates from her husband Jamie Gilbert
Countdown co-presenter Rachel Riley has left her husband just over a year after they married.
The maths expert, who recently starred in Strictly Come Dancing, tied the knot with university sweetheart Jamie Gilbert last August.
A spokeswoman for the star confirmed the pair, who live in Thorpe Bay, Essex, had separated.
Riley, who replaced Carol Vorderman on the show in 2009, married in front of guests including co-star Nick Hewer.
She was the fifth star to be voted off this year's series of Strictly Come Dancing, losing the dance-off to Abbey Clancy.
Riley and partner, Pasha Kovalev, were unanimously voted off the BBC One show by judges after the head-to-head battle with the model, who is one of this year's main contenders.
The 27-year-old split up with Gilbert at the end of 2009 but told Countdown viewers that he had proposed to her on her 25th birthday in January 2011.
The Manchester United supporter was given a bunch of flowers by Ryan Giggs on her 1,000th episode in June.
She also co-presents The Gadget Show on Channel 5 with Jason Bradbury.
