CHRISTINE McGuinness revealed her very toned tum in a sports bra as she worked up a sweat in her home gym.

The 35-year-old showed off some work out kit for a sponsored advert on Instagram.

Christine looked incredible wearing a selection of sports bras and leggings from H-e-r.

The star displayed her hard rock abs in some blue leggings and a black top as she posed for a selfie in the mirror.

Christine said: "Ma's a happy Ma. Feeling good!"

It comes after Christine and Paddy McGuinness celebrated their twins' 10th birthday.

TV presenter Paddy, 49, celebrated the big milestone with his estranged wife Christine at their Cheshire home.

Despite calling time on their marriage last year, Paddy and Christine still live in the family home for the sake of their children.

Posting on their Instagram accounts, they showed off the incredible bash they put on for Penelope and Leo who both turned 10.

Days before Christine flashed her underboob as she stripped off to a barely-there bikini in the heatwave.

The 35-year-old stripped down to a two-piece swimsuit and sarong as part of a sponsored ad on Instagram.

Christine left little to the imagination as she posed in a purple and blue tie-dye bikini top.

She completed the look with matching bottoms and a sarong wrapped around her waist.

Christine also went braless in an ultra-short purple dress.
