Celebs you never knew were parents to twins

Don't be fooled by the rocks (and hot body) that she's got: "Jenny From the Block" has twins! In 2008, Lopez welcomed twins Emme and Max with ex-husband, Marc Anthony, on Feb. 28.

To find adorable pictures of the twins, you need look no further than J-Lo's Instagram account; however, even though Lopez has 58 million Instagram followers and counting, their mama's social media accounts are by no means Max and Emme's biggest stage. Yep, at the young age of two, the adorable youngsters were featured with their mama in a campaign for Gucci. They've also graced the cover of People not once, but twice! Not too shabby considering they haven't even hit double digits. With a multi-talented mom like J-Lo, the sky is the limit for what these two can do.

Everyone knows that Ricky Martin has been "livin' la vida loca" for quite some time now, but what you may not know is that part of said "vida loca" includes his twin boys, Matteo and Valentino. The twins were born in August 2008 via a surrogate mother. In an interview with People, Martin talked about how he considered adoption but ultimately decided surrogacy was the more intriguing option because he was ready to jump into fatherhood. These days, you can find the 8-year-old Martin boys on the road with their dad not only as his biggest fans, but also as his biggest critics.

Although to the world Nancy Grace is best known for her candid commentary on high-profile cases, to Lucy Elizabeth and John David, she's just mom. At the age of 47, Grace didn't think that she would be able to start a family; but despite some initial complications prior to the twins' birth, her little boy and girl came into the world in November 2007. Grace lovingly refers to them as her miracle babies. Both are named in honor of family member's on both sides. While Grace is probably an awesome mom, based on her TV show, we're sure that those kids don't get away with anything.

Neil Patrick Harris and his husband, David Burtka, welcomed Harper Grace and Gideon Scott into the world in October 2010 via a surrogate mother. What is interesting about how Harris and Burtka's surrogacy process was that there were two different eggs involved. "We inserted one of my sperm and one of David's sperm into two eggs with the hope that they would both take, just because we both wanted to be dads biologically." And not to spoil anything, but they both did take! What all that means is that they are both the biological father of one of the twins – but they don't know which. However these days, Harris and Burtka have a pretty good idea of who's kid is whose. Burtka thinks that Harper Grace is his while Harris totally claims Gideon Scott.

Carrie Bradshaw might have had Samantha, Charlotte and Cynthia, but Sarah Jessica Parker has just as many (if not more) adventures with her twin daughters Marion Loretta Elwell and Tabitha Hodge as well as oldest son, James Wilkie. Although the names Elwell and Hodge might sound a bit "out there" to us, they are actually both names from SJP's side of the family. Since the girls' birth in 2009, Parker has tried her best to keep them out of the spotlight, which makes the rare snaps that she shares of the twins even sweeter. The most recent picture Parker posted of the twins on social media was an Instagram post to celebrate their seventh birthday in 2016. The picture shows the twins running around outside and in the caption Parker praises her "lovely, funny, dear, surprising, sparkling and beloved" daughters.

When she isn't adding names to the list of people she doesn't know or taking to the stage to stir up the latest bit of controversy, Mariah Carey is taking care of her two little "dahlings," Monroe and Moroccan. On April 30, 2011, instead of celebrating their third wedding anniversary with a nice dinner or night on the town, Carey and ex-husband Nick Cannon found themselves in the hospital waiting on the arrival of their twins. Monroe and Moroccan were stealing the show before they were out of the womb – only Carey's kids. Known affectionately by Cannon as Roc Roe, the twins have interesting stories behind their unique names.Moroccan was named after the Moroccan decor in Carey's New York City apartment as well as for the place of his parent's engagement, Morocco. Monroe was named after Marilyn Monroe, one of Carey's inspirations.

Although Carey and Cannon split in 2016 after five years of marriage, the two have become co-parenting experts. Whether the pair are reuniting for a sweet Mother's Day outing or just a family dinner, Monroe and Moroccan are the glue that keeps Carey and Cannon close.
