Sept. 11 (UPI) -- Kailyn Lowry posted a photo of Chris Lopez bonding with their newborn son over the weekend.
The 25-year-old Teen Mom 2 star captured a sweet moment between Lopez and their baby boy Sunday.
"Are they twins or," she captioned the picture on Instagram Stories.
Lowry welcomed "Baby Lo" on Aug. 5, but has yet to announce her son's legal name. She also has yet to confirm her relationship status with Lopez, although the new dad did say Sept. 6 that he's part of his son's life.
"Seen my lil man almost everyday..boom there the truth," he tweeted.
Lowry had said in an interview with Radar Online in August that Lopez will be a father to their child.
"[I'm] positive he'll be around," the star asserted. "I think every child deserves a dad."
"He does the best to his ability even though it doesn't necessarily meet the standards of what everyone else expects of him," she added. "I think people need to keep that in mind."
Lowry is also parent to 7-year-old son Isaac with ex-boyfriend Jo Rivera and 3-year-old son Lincoln with ex-husband Javi Marroquin. She came to fame on the MTV series 16 & Pregnant before starring on Teen Mom 2.
