CHELSEE Healey took on the Battle of the Backsides Celebrity Sit Off challenge this week as she attempted to sit on as many chairs as possible in two minutes - we love the people who make this stuff up.Â
Tulisa's best pal made an appearance at Wembley stadium for Alan Shearer and Robbie Savage's Sport Relief competition.
Not exactly dressed for the occasion, the 25-year-old donned a pair of tight 'oldskool' Burberry trousers.
But that didn't slow her down on the brutal task - covering an impressive 105 seats in the two minutes, Chelsee finished just 41 seats behind current leader, McBusted’s Harry Judd.Â

She later tweeted: "Just been down to wembley to see @RobbieSavage8 and Alan shearer on their sport relief challenge. Wow not sure how you will get though it." Â
