TLC star Tionne 'T-Boz' Watkins has found there's only one room in her house she can comfortably sleep in - her screening room.

The 35-year-old WATERFALLS singer has been living in the plush Atlanta, Georgia, mansion for the past four years, and while her home boasts seven bedrooms, her screening room - outfitted with leather recliners and a popcorn machine - is the place she's guaranteed to be found fast asleep.

She says, "I have insomnia, and that's the only room I can sleep in!"

Watkins' home also boasts a gym, mini-salon and an indoor waterfall in the foyer - recalling her 1995 hit.
