Kailyn Lowry took to Twitter on Sunday to post a cryptic message about being "loyal," just days after rumors surfaced that the "Teen Mom 2" star may have got back with her third baby daddy, Chris Lopez. Lowry is currently pregnant with her third child and is due in the next few weeks.

"When you're loyal behind my back THEN I will be impressed," Lowry wrote in a tweet, which was preceded by another that said, "Nothing surprises me anymore."

The mother-to-be gained a lot of social media attention since the time she announced her third pregnancy in February but decided to keep the identity of baby's daddy a secret. Many speculated Tyler Hill, JC Cueva, or Lopez of being the father until Lowry made the revelation earlier in May. However, it was later revealed that Lowry was no longer with Lopez.

However, the Grace Report shared a video with fans May 30 in which claimed to have proof of the former couple's alleged reunion.

The 25-year-old welcomed a French bulldog puppy into her family recently and after a photo of the dog was shared on Instagram, Lopez mentioned the pup’s name on his Twitter page. Lowry, on her Snapchat account, confirmed the dog belonged to her and revealed the bulldog’s name was "Gotti." A short time later, Lopez tweeted a post which mentioned "Gotti" before quickly deleting the tweet from his page. "Gotti goin' be tuff," read his now-deleted tweet which sparked rumors of them getting back together.

Tensions between Lowry and Lopez were seen after The Ashley’s Reality Roundup released photos of the latter with a mystery woman in bed. The Snapchat photos, which were shared last month, showed Lopez cuddling with the unidentified woman.

“I wish him nothing but the best and I hope he finds happiness with her or whoever he may or may not be with,” Lowry said in response to the photos.

The photos came just days after Lowry posted a picture of herself in bed with another man. Soon after the picture went viral, she was photographed in California with the mystery man.

Lowry's ex-husband Javi Marroquin slammed the pregnant MTV reality star for posting pictures with another man. Marroquin is the father of Lowry's 3-year-old son Lincoln. She also has a 7-year-old son, Isaac, with her ex-boyfriend Jo Rivera.

“It’s just sad. It makes me sad for the boys. I have nothing else to say about her,” he told Radar Online in an exclusive interview. Just after Lowry had posted the pictures on social media, Marroquin tweeted, “I’m disgusted.”

Meanwhile, Marroquin also said last month he was planning to take legal action against Lowry as he does not want to take any responsibility for Lowry's third child.

“I’m doing what I have to in case she doesn’t put him on [the birth certificate],” Marroquin, 24, said of Lopez to Radar Online. “I’m talking to my attorney right now.” Marroquin, who shares son Lincoln, 3, with Lowry, added, “I’m not worried about it!”

As the celebrity gossip website had earlier reported, citing New York Attorney Brooke A. Camhi that Delaware law states “the ex-husband is presumed the father of a child if the child is born less than 300 days after the divorce.”

While Marroquin has maintained a relationship with Lowry’s son Isaac, 7, whom she had with ex-boyfriend Jo Rivera, he told Radar Online earlier this month he “won’t have a relationship with the new baby.”
