But Rob and Kristen aren't the only Hollywood hotties who have struggled with infidelity — just look at MTV's Teen Moms. Although cheating can sometimes be the death of a relationship, there may be light at the end of the tunnel, y'all. If K-Stew and R-Patz can get through it, we have no doubt our Teen Moms will too.
Read on to find out which ladies and gents have been unfaithful!
Maci went on the rebound with supercross racer, Kyle Regal, shortly after breaking up with Kyle King, but he turned out to be completely untrustworthy.
The details of Kyle and Maci's split are still mysterious, but apparently Kyle asked singer Cady Groves to send him nude photos. Cady is friends with Maci, who quickly found out about Kyle's betrayal and broke off the relationship. You go girl!
Cate and Ty are the sweetest, most committed couple in Teen Mom history, but even they have been through their ups and downs. Shortly after getting engaged, Catelynn told Tyler that she had cheated on him two years prior.
"It might sound stupid, but I lied about sleeping with my ex and texting him because I was scared of hurting Tyler," she told MTV at the time. "I learned the hard way that lying doesn't work because it only hurt him more."
Catelynn's infidelity definitely hurt the relationship (ya listening, Kstew?), but Tyler forgave her and they've been living happily ever after ever since. There's hope for Robsten yet!
Details of Gary's infidelity are still murky, but apparently he was unhappy with Amber and struck up a flirtation with some girl in the diaper section of Walmart (go figure). Gary says he asked Ambs for some time to figure out who he wanted to date, and then decided to stick with his baby mama.
"Never cheated on Amber," Gary tweeted. "She may have thought I did, but haven’t. I will always love and respect her even if we aren’t together."
Leahcheated on her then-husband, Corey Simms, just a few weeks before their wedding –– and it wasn't the first time. Leah first locked lips with her ex-boyfriend, Robbie, shortly after her twins were born, and poor Corey just couldn't take it.
"I'm not trying to make any excuses for it, I'm really not," Leah told Dr. Drew during the Teen Mom 2 Reunion Special, "but we weren't having sex, we weren't being intimate. We'd go to bed and he would turn the other way. I was crying 'til, like, three o'clock in the morning. Like, please be loving with me. Something. And it didn't matter to him whether we did it or not."
Adam Lind Repeatedly Cheated on Chelsea Houska Kristen Stewart made a one-off mistake when she cheated on Robert Pattinson, but Chelsea's baby daddy, Adam, is a serial heartbreaker. During Adam and Chelsea's televised breakup on Teen Mom 2, he admitted to cheating on her a total of five times. That's right, as in more than once. Shaking our heads in disappointment. Gary Head andJenelle Evans (Reportedly) Cheated on Each Other
Jenelle and her ex-fiance, Gary, had an extremely rocky relationship, and they both accused the other of cheating. Jenelle claimed that Gary slept with her ex-bestie, Victoria Rhyne, but he insists he slept with Tori two weeks before he started dating Jenelle.
Meanwhile, Gary accused Jenelle of cheating with her ex-boyfriend, Kieffer Delp, after their engagement. Sigh, who knows what to believe. Rob and Kristen should count themselves lucky … it could be so much worse!
