Big Sean, 25, is engaged to “Glee” star Naya Rivera, just months after the pair began dating. Rivera, 26, showed off her diamond engagement ring for the first time at Latina magazine’s Hollywood Hot List Party on Thursday.

The two recently went public with their engagement after they were inseparable at the "42" film premiere’s red carpet event in April.

“Naya and Sean were taking pictures together all night -- they were doing a lot of selfies on their phones. They looked so happy to be together. It was like they wanted to document every second," a source told Perez Hilton about the couple at the time. 

"They were holding hands most of the night, and, when they left together, Sean was walking with his arm around Naya; he seemed really protective of her.”

The “G.O.O.D.” rapper confirmed his relationship with her shortly afterward, on WKYS’ Urban Informer program. “Naya, I been dating her for a little while, and I guess that event [the "42" premiere] was one of the first big events that came up while I was dating her.

"We were like, 'Yo, let's go to it,' because we both wanted to go. I'm kinda a private person, and she's a private person. ... As far as Naya, it's something new. Naya's really cool. Our relationship is cool. She's tight,” he said, according to MTV.

He then went on to gush about the beauty, telling E! News, “Every morning I wake up, I look over at her and be like, ‘I'm winning so hard.’”

Prior to Rivera, Big Sean had a longtime relationship with his high school sweetheart, Ashley Marie, but they broke up earlier this year. He spoke about their breakup on WKYS, saying, “I had a girlfriend too before that who I was with since I was like ... I always been in a relationship since I was 18 or 19 when I got with her [sic]. Things didn't work out and not because of this music stuff.  But sometimes when you're with somebody and you're 18 and you grow up ... and it's long distance because she lived in New York and I lived in L.A ... you grow apart as people.  It's nothing more and nothing less. 

"It's not like I've changed. It's not like that at all. We just really had our differences and it just clearly didn't work out.  It may work out later, it may come back, too. Who knows.”
