Elle Macpherson turns 45 on March 29. May she have another 45 rockin' bikini bod years to come.
Celine Dion turns 41 on March 30. We wish her another year of sold-out tours, though we don't think she needs much help with that.
M.C. Hammer turns 47 on March 30. We wish he would get a gig on another celebrity reality show. Any interest, "Dancing With the Stars"?
Norah Jones turns 30 on March 30. We wish she would come out with a new album. Please?
Ian Ziering turns 45 on March 30. We're hoping Ian makes a cameo on "90210," hitting on 18-year-old high school girls like Matthew McConaughey in "Dazed and Confused."
Christopher Walken turns 66 on March 31. For Walken, we wish that hacky comedians would stop doing terrible impressions of him. Seriously.
Ewan McGregor turns 38 on March 31. We hope his risky "Brokeback Mountain"-meets-"I Love You, Man" film, "I Love You Phillip Morris," finds a distributor.
"Girls Gone Wild" CEO Joe Francis turns 36 on April 1. We wish he would go away.
Bijou Phillips turns 29 on April 1. We wish that she and her new fiance/co-star Danny Masterson have an adorably indie wedding.
Christopher Meloni turns 48 on April 2. Hoping his show "Law & Order: SVU" continues for another decade. We're guessing it will.
Eddie Murphy turns 48 on April 3. We wish he'd land a dark, gritty drama … but still play all the characters in the movie.
Alec Baldwin turns 51 on April 3. May he avoid leaving any voice messages this year and stick to his hilarious "30 Rock" antics instead.
Jamie Lynn Spears turns 18 on April 4. Now coming into adulthood, we wish she'd behave a little less like an adult.
Robert Downey, Jr. turns 44 on April 4. Wishing he'd stop getting hotter with age. It's just not fair.
