Stacy Keibler tweeted a picture of herself mid workout with a pal – and it was hard to miss her impressive abs in the shot.
Friends of the former pro wrestler dismissed the reports she is expecting with George Clooney as "100 per cent false" to TMZ.
And the snap seemed to confirm this. Stacy posted it on Twitter, announcing she had joined picture-sharing app Instragram.
She told her followers she was exercising to Barry's Bootcamp DVD – which is popular with celebs including Kim Kardashian.
"It hurts," Stacy wrote alongside the hashtag 'notjoking'.
The pretty blonde is currently in italy celebrating her one-year anniversary with gorgeous George.
They were spotted holding hands during a candlit dinner earlier this week near Lake Como, where george owns a spetacular waterside villa.
George and the statuesque beauty have been dating since July 2011.
