What's keeping Bips up these nights?

MUMBAI: Bipasha Basu is sleep-deprived these days. But before the naughty thoughts take a flight, the actress bursts the bubble by revealing the real reason behind her sleepless state. “It’s only work, and some more work,” she states laughingly. The Bong beauty has been shooting all night through since the past few days. But surprisingly, that sleep-starved look barely shows on her fresh-as-ever-face. Spilling the beans on that secret, Bips adds, “I have been trying to catch up on my sleep during the day-time.” Which is not much, we think, considering the freqeunt public appearances the actress has been putting in off late for her recent film. Now, how and when the actress manages to catch on her beauty sleep is a mystery waiting to be solved. Any help John?
