The Teen Mom 3 alum revealed that she welcomed her second baby on Sunday, her first with husband Tim Peters.

On Tuesday, Sekella, 28, announced Althea Meredith Peters' arrival in a precious Instagram post featuring a trio of snapshots.

"I would like to introduce ALTHEA MEREDITH PETERS Born 1.30.22 5:12am 7.12lbs 18.5" long," Sekella — who was first introduced to fans on season 4 of 16 and Pregnant in 2012 — wrote in the caption.

One shot shows baby Althea donning a pink onesie that reads, "Happy Little Princess," while the proud parents pose with the newest addition to their family in another picture.

Althea joins 10-year-old Arabella, whom Sekella welcomed with ex Matt McCann in 2011.

According to an Instagram post by Sekella earlier this month, Peters officially adopted her older daughter a week before baby Althea's arrival.
