It's a girl for former Teen Mom 2 star Megan Nelson! Chelsea Houska's ex-bestie gave birth to Raelynn Elaine on July 25, and she is PRECIOUS. Yesterday, the mom-of-two — who welcomed son Hunter in 2011 — took to Instagram to post a photo of her new bundle of joy.

Before Chelsea's handsome husband, Cole DeBoer, came into the picture, Chelsea and lookalike Megan were inseparable. She's an esthetician like Chels — they were in beauty school together! — but these days, the two are no longer friends. They had a falling out when Chelsea's baby first baby daddy, Adam Lind, moved into the house they shared together. At the time, she said, "I hate him. I’m not mad at you, I just don’t like the situation. I want to be [friends], but it’s going to take a long time if you and Adam are together." Turns out, she had good instincts!

Adam has been making headlines recently for his drug use. The troubled star tested positive for meth and amphetamines after taking a court-mandated, random drug test and may now lose custody of his daughter, Paislee, 3, — who he shares with ex Taylor Halbur. Adam also has daughter Aubree, 7, with Chelsea.

Despite this baby daddy drama, we hope that Chels and Meg can make amends. After all, since Chelsea gave birth to son Watson Cole back in January, now would be the perfect time to schedule a play date.

Teen Mom 2 airs Monday nights at 9 p.m. EST on MTV.
