"Teen Mom 2" star Kailyn Lowry gave fans a first glimpse of "Baby Lo" this week.

The 25-year-old television personality posted a picture of the infant Wednesday on Instagram after welcoming her third son Aug. 5.

"Baby Lo," she captioned the snapshot for her 3.1 million followers, adding a blue heart emoji.

Lowry has yet to officially name her newest addition. She is already parent to 7-year-old son Isaac with ex-boyfriend Jo Rivera and 3-year-old son Lincoln with ex-husband Javi Marroquin.

"Still trying to pick one," the star tweeted Monday. "I think I'm overthinking it."

"Isaac said the name Murphy was 'eh, okay... for a dog,' and also suggested Francis," she added Wednesday. "linc is still adamant about naming baby Lo 'climber.'"

Lowry confirmed Baby Lo's birth Saturday after Radar Online reported she welcomed her son at 3 a.m.

She shares her son with Chris Lopez, but said in a since-deleted post in April that she will be raising the child alone.

"I think I'm most worried about the changes ahead but also that I will have this baby 24/7 by myself with no help," the star wrote. "I'm going to be a single parent from the beginning!"

Lowry came to fame on the MTV series "16 & Pregnant" before starring on "Teen Mom 2." The show airs Mondays, and co-stars Jenelle Evans, Chelsea Houska, Leah Messer and Briana DeJesus.
