Our baby?

The two friends were rumored to be dating last summer following Kailyn's split with Javi Marroquin — but, Kailyn shut down the rumors immediately.

“Becky and I are just friends. That’s it. We are not in a romantic relationship at all," she said. "There’s nothing more to it. In fact, Becky is talking to someone else she’s interested in.”

Kailyn confirmed her most recent pregnancy on Feb. 23 in a blog post on her website, after sources had already come forward admitting the mom-of-two was pregnant again.

"I am pregnant. I’m sad that I should have known that people in my life would sell me out before I was ready. Like any normal person, I want it to be a happy time. I wanted this to be a private time so I could be excited while not getting chased by paparazzi and bothered with crazy headlines," she revealed. "Please know this was a choice I made, I already know some won’t agree but I’ve been showered with support by the ones I love since I found out."

Well, it's only a matter of time until her mystery man comes forward!
