It looks like Travis McCoy is following in friend/label mate Pete Wentz's footsteps. The Gym Class Heroes front man has given his GF Katy Perry a promise ring! Katy wears the diamond bauble on her left middle finger, while Travis wears a silver band that says 'Katy' on it. "I went in [to the jewelry store] and said I wanted a ring," Travis tells People. "The lady behind the counter said, 'Here's one for $300.' I was like, 'I want a nice ring!' Then I pointed to the big one." Trav says he was "so scared to give it to her," but Katy made him feel better. "She was so excited! And I'd set up flowers everywhere." Too cute!

Could a real proposal be far behind? Travis stayed coy about that…
