Dating Bombshell! Kailyn Lowry Tells All On New Man After Ditching Baby Daddy Chris

Kailyn Lowry has moved on to a new man after ending her romance with baby daddy Chris Lopez, but how serious is she getting with Dionisio Cephas? In an exclusive interview with RadarOnline.com, the Teen Mom 2 star tells all on her romance with her hot new man.

Lowry, 25, sparked relationship rumors when she posted a Snapchat photo of Cephas.

She then tweeted, "What are the chances I'll actually see @ttc1 today?"

When he responded, "Stop acting like I don't live next door," she replied, "Long distance relationship with the guy next door."

But Lowry sparked trouble in paradise when she tweeted over the weekend, "Just when you think you like someone they'll give you a cool 5 reasons you're wasting your time."

Lowry told RadarOnline.com of their romance, "I wouldn't say we're dating. I'm not dating anyone. But if I was going to date anyone, it would be him."

As for Cephas, he told RadarOnline.com, "No, we are not dating yet. Time will tell. Everything is fine as far as I know."

Cephas was the shirtless man Lowry was caught in bed with in May during a trip to Los Angeles. The photo caused controversy, as she was seven months pregnant with Lopez's son at the time.

Lowry welcomed her third son Lux Russell with ex-boyfriend Lopez in August. She is also mother to Isaac, 7, with ex-boyfriend Jo Rivera and Lincoln, 3, with ex-husband Javi Marroquin.

Lowry moving on comes after she slammed Lopez by giving their son her last name instead of his.

A source told RadarOnline.com that her decision came after Lopez refused to acknowledge paternity of Lux.

"My guess is he won't acknowledge paternity so she can't file for child support," an insider close to Lowry told RadarOnline.com. "They give a form in the hospital, but he didn't sign it."

The source revealed that Lowry is now taking legal action to ensure her baby daddy steps up as a father.
