1. Kristin Cavallari
Kristin Cavallari and Jay Cutler have gotten engaged, broken up, and then gotten engaged again, but it's a good thing they're back together now because they have adorable little Camden together. She gave birth to him last year when she was 25.
We were shocked to find out that Adele just turned 25, because the girl's talent is beyond her years. And she gave birth to her son, whose name still hasn't been revealed, at just 24, which is also mind-boggling. We need to see that baby already!
3. Britney Spears
Brit married Kevin Federline in 2004 and welcomed her first son, Sean Preston, into the world in 2005 when she was just barely 25. Then a year after that came Jayden James. Brit's definitely a young mom but she's also a hot one, so whatever.
4. Ashlee Simpson
Ashlee and Pete Wentz got married in 2004 when she was pregnant with their son Bronx, who was born when Ash was 24.
5. Hilary Duff
Hilary got pregnant with her husband Mike Comrie about a year into their marriage. Now, Hil's only 25 but has the cutest son, Luca, who's just over a year old.
6. Jacqueline Laurita
The 'Real Housewives of New Jersey' star gave birth to her daughter, Ashley, when she was only 20. Now, Jackie's got two other kids (both boys) and a happy marriage to her hubby Chris, so we'd say she's doing juuuuuust fine.
7. Kendra Wilkinson
Kendra and Hank got hitched when she was a few months preggers with baby Hank, who was born in 2009 when Kendra was 24. And now look at them. Happy as can be!
8. Kim Zolciak
Kim, of 'Don't Be Tardy,' had her first daughter, Brielle, at just 18. Now she has 4 kids total, two of which are with her ultra hunky football player husband, Kroy Biermann. Some girls have all the luck.
9. Solange Knowles
Solange got married really young and gave birth to her son, Daniel, when she was just 18. She and her husband later divorced, but they still co-parent Daniel together. How cute.
10. Reese Witherspoon
Before the days of Jim Toth and baby Tennessee, Reese had her lookalike daughter Ava with her then-husband Ryan Phillippe when she was just 23.
The reformed 'Jersey Shore' star got knocked up when she was just 23. Now, she and Jionni are parents to Lorenzo, the cutest guido baby ever, and engaged! My, how things changed.
