OK! Exclusive: Leah and Jeremy Almost Call It Quits on This Week's Teen Mom 2

Rihanna talking about Jenelle Evans on Facebook? What has the world come to? To promote her upcoming tour with Eminem, Rihanna posted a clip from that infamous episode of Teen Mom 2 where Jenelle tells Dustin she can't go to jail because she has tickets to a Ke$ha concert. It is actually HILARIOUS, mainly because like, who knew RiRi was a fan of the show, you know?

Also, in other Jenelle Evans headlines, Jenelle tweeted cryptic tweets about a major gift that Nathan purchased for her. We know it has four wheels and goes in the driveaway, but is it a car? A motorcycle? A toy car for their soon-to-be-born little boy, Kaiser? Time will tell.

Leah Messer tweeted a few weeks ago about how she was getting ready for a surgery, and now we finally know that Leah went under the knife to get her wisdom teeth out! She tweeted this selfie of her chipmunk-like face in pain after the procedure. Feel better, Leah.

Leah's ex Corey Simms, meanwhile, is making some changes to his face, too—check out that facial hair! In this new Twitter photo, Corey's beard is longer than ever, even longer than it is on the show right now! Just one question—Is it itchy?

And in other Twitter news, you've probably heard by now that Amber Portwood has joined and you can follow her @AmberLPortwood! Aside from tweeting about how supportive her fans have been in her quest to remain sober, Amber has also used the social network to reconnect with her Teen Mom co-star, Maci Bookout. After a fan tweeted a pic at the girls of when she met the cast in Times Square, Maci and Amber started up a convo talking about the good times they had in NYC and how they miss each other. Perhaps they'll be seeing each other sooner than later for that rumored Teen Mom reunion special...

POLL: Would You Watch a Teen Mom Reunion Without Farrah Abraham?

Farrah Abraham, meanwhile, is working on her newfound music career, but her dad's keeping busy himself. Celebuzz and other outlets report that Farrah's dad, Michael, is working on a book that will talk about "being a parent to Farrah and Sophia," and what it's like being on a reality TV show. He also promises that the book will discuss things never talked about on the show, and of course, that sex tape. Well..good for him.

We know from the Being Catelynn special that Catelynn Lowell and Tyler Baltierra make part of their living by doing motivational speeches about adoption and stuff, and now, they're taking their talents across the pond! Catelynn shared a photo on Instagram saying that they'll be doing a speaking engagement and meet and greet at the Love Life Festival in Dublin on April 11, where attendees can hear inspiring stories from young people who have dealt with hardships. Catch the couple in the festival's promo video at about the :42 mark:
