THIS ‘Teen Mom 3’ Alum Just Welcomed Her 2nd Child!

Congratulations are in order for Alex Sekella and Tim Peters!

Over the weekend, the “Teen Mom 3” alum revealed on Instagram that she and her husband welcomed a beautiful baby girl named Althea Meredith Peters.

The bundle of joy was delivered January 30 at 5:12 a.m. The cute tot weighed in at 7.12 lbs. and measured 18.5 inches long.

While this is Alex’s second child, it’s her first with Tim.

“I would like to introduce ALTHEA MEREDITH PETERS,” Alex wrote over a carousel of images, including one of Althea wearing an adorable pink onesie.

Earlier this month, Alex revealed on Instagram that Tim officially adopted her firstborn, 10-year-old Arabella, just a week before Althea’s arrival.

“It has been a VERY VERY LONG process but we can finally say Arabella is a PETERS!! 🎉,” Alex captioned a photo of the family at a courthouse.

After dating for over four years, Alex and Tim got engaged in December 2018 around Christmas.

“A few days ago this incredible man asked me to be his wife. @timpeters24 #happilyeverafter,” she wrote on Instagram.

Years later, the two officially tied the knot on April 25, 2020.

Alex first appeared on Season 4 of “16 and Pregnant,” which chronicled the birth of Arabella, whom she welcomed with her then-boyfriend Matt McCann.

After the two split, Alex appeared in 2013’s “Teen Mom 3,” which documented their rocky relationship and Matt’s reported addiction issues.

The “Teen Mom” spin-off — which also featured mothers including Briana DeJesus, Mackenzie McKee, and Katie Yeager — only lasted one season.
