Word on the street is that Teen Mom's Catelynn Lowell and her hubby-to-be Tyler Baltierra have joined the cast of Vh1's Couples Therapy — and while the reality star isn't denying that piece of news, she is denying being pregnant again.

When a fan on Twitter questioned Catelynn about the latter, she responded with a resounding "NOT TRUE." And since it's written in caps you know she means business.

So how did this rumor start in the first place? We have no idea, considering that Catelynn and Tyler are currently putting their careers first. Just look at their recent string of cryptic tweets and sudden move to Los Angeles, which they've been teasing nonstop on Twitter. Catelynn even said fans would "freak" over their new endeavor.

At first we assumed they were working on a wedding spin-off (they're planning to get hitched on July 13, 2013), and then we thought maybe Tyler had landed a major acting gig. But now, with this new Couples Therapy report from TMZ, we're all kinds of confused about what Catelynn and Tyler have up their sleeves.

And to make matters even more confusing, Teen Mom 2's Kailyn Lowry just revealed that Couples Therapy producers approached her and husband Javi Marroquin — but they turned down the opportunity because Javi's away at Air Force training.

And the plot thickens! But at least we can rule out another baby ... for now. Do you think Catelynn's telling the truth? Tell us below, Teen Mom fans!
