Nicolette Sheridan is reportedly pregnant with her first child.
The "Desperate Housewives" star - who is engaged to singer Michael Bolton - is thrilled after discovering she is expecting.
A show source said, "She's absolutely glowing and her pregnancy is the buzz of the set."
The 43-year-old actress has been asking her co-stars Marcia Cross and Felicity Hoffman for advice on pregnancy and motherhood.
The source added, "She kept asking Felicity and Marcia about how the pregnancy would change her appearance and if it would make her hair thinner."
Nicolette - who got engaged to Michael in March 2006 - recently revealed her desire to become a mother, even though she has a hectic lifestyle.
She said, "I don't know how I'd have time to deal with it, but being a mom is so special. Of course, if it happened, I would just make time!"
Michael, 53, already has three daughters from his marriage to Maureen McGuire. Nicolette and Michael first dated in the 90s and rekindled their romance in 2005.
