You might be surprised to see how many celebs are keeping busy raising twins! Here are some parents who are twice as proud.
10. Charlie Sheen
Charlie Sheen and Brooke Mueller welcomed Bob and Max on March 14, 2009. The couple is no longer together, but their sons are still totally adorable.
11. Tito Ortiz and Jenna Jameson
The ultimate tough guy and arguably the world's most popular porn star welcomed their twins on March 16, 2009. Born a few weeks early, the twins, Jesse Jameson Ortiz and Journey Jette Ortiz, weighed just over four pounds each. Now they're happy and healthy and have the cutest curly locks. Clearly they didn't get the hair from their dear old dad.
12. Kate Gosselin
While Jon and Kate Gosselin famously have eight children together, they started with two. Kate gave birth to twins Cara and Mady October 8, 2000. The next six were born in 2004.
13. Marcia Cross
Desperate Housewives star Marcia Cross gave birth to fraternal twin daughters Eden and Savannah February 20, 2007, shortly before her 45th birthday. She and husband Tom Mahoney have also talked about adopting another baby in the future.
14. Molly Ringwald
Molly Ringwald gave birth to twins Adele Georgiana and Roman Stylianos on July 10, 2009. She was very pregnant while filming the show The Secret Life of the American Teenager, but it all worked out. Her pregnancy was written in as a plot point.
15. Ricky Martin
Ricky Martin's twin sons, Matteo and Valentino were born in August 2008, thanks to a surrogate mother. The singer still keeps in touch with her and said in an interview: "I would give my life to the woman who helped me bring my children into the world."
16. Lance Armstrong
Lance Armstrong's ex-wife, Kristin Richard, gave birth to the couple's twin daughters in 2001, three years after Lance's cancer was found to be in complete remission. The pregnancy was made possible thanks to sperm that Lance had banked before his battle with the disease.
17. Ray Romano
Ray Romano's kids had recurring roles on his sitcom Everybody Loves Raymond, and his on-screen twins were even named after his identical twin boys, Gregory and Matthew. That is, until he had the characters' names changed because it was too creepy.
