Dancing doesn't get tougher than this - Masterchef presenter Gregg Wallace is set to join the line-up for this year's Strictly Come Dancing, according to reports.

The south London greengrocer-turned TV star will join Bargain Hunt's Tim Wonnacott and Mrs Brown's Boys star Jennifer Gibney, according to The Sun.

They are expected to be unveiled tonight (Friday) on The One Show.

Confirmed cast members include f ormer Xtra Factor host Caroline Flack, singer Frankie Bridge, Judy Murray, Mark Wright and Pixie Lott.

The new series will be the first without veteran host Sir Bruce Forsyth, with Tess Daly and Claudia Winkleman sharing the presenting job.

Tess, 45, said she and Claudia, 42, had proved they were not past their "sell-by date" by fronting the show together.

She said she is proud to be championing "Girl Power".

She told Good Housekeeping magazine: "I know - two women hosting the biggest show on TV! And in our 40s ... Surprise, surprise, we're not past our sell-by date.

"It's a huge compliment that the BBC has broken the traditional male/female hosting format, and all credit to them for being the first to do it. I saw Geri Halliwell at an event recently, and she actually said the words 'Girl Power' to me. I loved that."

Strictly Come Dancing returns to BBC One for its 12th series on Sunday September 7 at 8pm.

Tess has co-hosted the show with Sir Bruce, 86, since it began in 2004 and was joined by Claudia in 2011 to present the Sunday night results shows.
