Halle Berry already turned heads once by giving birth at the age of 41 to now 5-year-old daughter Nahla, but she's raising the bar even further this time by announcing her next pregnancy at the age of 46!

A rep for the actress announced over the weekend that Halle is three months pregnant and will be having a boy. It's her second child and first with fiance Olivier Martinez. "Halle and Olivier are really excited. It's a blessing. They can't wait to have a baby together," said a source to E! News.

While giving birth at 46 is certainly uncommon, the women of Hollywood are apparently quite fertile because they've had babies in their middle age on numerous occasions. Check out our roundup of 9 other celebrities who have gotten pregnant over the age of 40!

Madonna is certainly in good enough shape to have kids later on in life. After giving birth at age 38 to daughter Lourdes, she welcomed her second child and first with ex-hubby Guy Ritchie in August 2000, a boy named Rocco.

2. Julianne Moore

Julianne already had a 14-year-old boy named Cal with her husband, director Bart Freundlich, but gave birth to her daughter Liv in April 2002 at the age of 42. "The funny thing is I was determined to have a baby by the time I was 36. My son was born the day after my 37th birthday. He was three weeks late. It was like the universe was laughing, saying, ‘You see, you can’t control things,'" she recalled.

3. Tina Fey

Tina already had a daughter, but admitted that she felt guilty every time her young child said, "I wish I had a baby sister." In August 2011, she gave birth at the age of 41 to her second child, daughter Penelope Athena. "What's so great about work anyway? Work won't visit you when you're old. Work won't drive you to get a mammogram and take you out after for soup," she wrote in her memoir Bossypants.

4. Nicole Kidman

Nicole already had two adopted children with her ex-husband Tom Cruise, but gave birth to her first biological child, daughter Sunday Rose, in July 2008 at the age of 40. She didn't stop there with her country superstar hubby Keith Urban, welcoming daughter Faith Margaret in December 2010 with the aid of a gestational carrier. “Struggling with fertility is such a big thing and it’s not something that I would run away from talking about. We were in a place of desperately wanting another child and I couldn’t get pregnant,” she said in February 2011. “I get emotional just talking about it because I’m so grateful.”

5. Uma Thurman

Uma already has two children with ex-husband Ethan Hawke, Maya, 14, and Levon, 11. However, she announced in March 2012 that she was pregnant with baby number three at the ripe old age of 41. She gave birth in July 2012 at age 42 to the most absurdly-named child of all time, Rosalind Arusha Arkadina Altalune Florence Thurman-Busson (or Luna, for short). The best part about this? The name wasn't revealed until last October, a full three months after Luna was born.

6. Mariah Carey

Is she pregnant or did she just gain weight? Mariah endured months of baby bump speculation before confirming that she was expecting with hubby Nick Cannon. It was hardly an easy road for the singer, though, with Mariah revealing that she suffered a miscarriage before becoming pregnant with twins and was ordered bed rest for several months. But at the age of 40, she gave birth to fraternal twins Monroe and Moroccan via C-section in April 2011. “I was so uncomfortable. Pregnancy with twins is different than anything," she said after the birth in July 2011. "They were always saying to me, ‘It’s all worth it.’ Yeah, it’s easy for you to say when you’re not the one whose feet are this big! It turned into a really difficult time.”

7. Kelly Preston

After she and hubby John Travolta endured the tragic death of their 16-year-old son Jett in January 2009, Kelly gave birth to another son Benjamin at the age of 48 in November 2010. "We had been trying for quite a few years, and then of course there was a time when we weren’t, and then we started trying again,” said Kelly in August 2011. “When I found out I was pregnant, I was floored. I’d snuck out of bed and then came back and woke Johnny up in bed. We both started crying. It was wonderful.”

8. Salma Hayek

Salma had her only child, daughter Valentina, in September 2007 at the age of 41 with her French billionaire husband François-Henri Pinault. But while some women claim to love being pregnant, Salma does not seem like she will be added to that list anytime soon. "You are like a swollen whale and never looked worse in your life. And somebody goes, ‘You’re glowing.’ They don’t have the courage to tell you how bad you look,” she said in 2009.

9. Celine Dion

Celine has been open for years about the desire to have a baby with her much-older husband René Angelil. But after several failed IVF attempts, she got her wish and gave birth at age 42 in October 2010 to fraternal twin boys, Nelson and Eddy. "I feel like I've been pregnant for more than a year," she said in May 2010. "I never gave up. But I can tell you that it was physically and emotionally exhausting."
