On the latest episode of “Teen Mom 2,” Chelsea celebrated her daughter Aubree’s 4th birthday with a huge backyard bash, but no amount of cake pops and bounce houses could keep her mind off the recent news that ex-boyfriend Adam’s girlfriend, Taylor, had just given birth to a baby girl.
“It’s annoying because I wanted a family and now he’s off having kids with other people,” Chelsea confided to her friend Chelsey Grace.
In this sneak peek of Tuesday’s new episode, Aubree spends some quality time getting to know her little half-sib, Paislee, and is already playing the part of protective big sis. As Adam and Aubree take turns holding the sleepy newborn, Aubs is all smiles, and tells her dad she can’t wait to introduce Paislee to her mom.
Adam’s response? “Have fun with that.”
Check out the clip, and tune in to “Teen Mom 2” Tuesday at 10/9c to see how Paislee’s arrival affects Chelsea and Adam’s already complicated relationship.
