Actress Kirstie Alley has laughed off a report she has traded her 21-year-old boyfriend for another toyboy lover.

The Cheers star, 60, dumped her young beau after discovering he still lives with his mother, according to Britain's Daily Mail newspaper.

The publication reports she has now taken up with another young man, and the feature is accompanied by photographs of the actress out on a lunch date with her unnamed admirer.

However, Alley took to her Twitter.com blog on Friday to laugh off the claims, sarcastically suggesting she has a string of toyboy lovers.

She writes, "Every single thing u (sic) read about me is true... why it seems I've sh**ged 200 men under 23 just this month alone!!... Lol (laugh out loud)... great pics though."
