Rumor Mill: Nicollette Sheridan Pregnant?

The Internet is abuzz with rumors that 43-year-old Desperate Housewives star Nicollette Sheridan is pregnant with fiancé Michael Bolton's child.

According to the online whispers, a source on the set of the hit ABC show is saying she's "absolutely glowing," and that Nicollette has been asking co-stars Marcia Cross and Felicity Huffman for pregnancy and mothering advice.

However, one club-hopping spy tells OK! they spotted the actress sneaking a couple cigarettes while hanging out in her private VIP booth at Moto9 at the Lot in West Hollywood earlier this week.

When contacted by OK! for a comment, Nicollette's rep tells OK! the rumors are "not true."
