That was quick! After six months of dating, Naya Rivera and Big Sean are engaged. And the rapper proposed to the Glee star with one big, blinding rock.

Rivera debuted her new bling — a godzilla-size cushion cut diamond surrounded by a halo of smaller diamonds on a thin pave band — Thursday night at Latina magazine’s Hollywood Hot List party. Our Celeb Style Council member paired the mini planet on her left hand with an on-trend nude mani and sophisticated ensemble: a vintage Armani top and silk Bec and Bridge trousers.

Back in July, the actress/singer told PEOPLE that her beau (the couple met on Twitter!) is always there to support her career.

“Sean and I have really similar tastes in music,” she shared. “Creatively he’s so good and talented at what he does, and he’s always giving me advice on my own music or how I should sound. I really value his opinion because he’s been doing it for a lot longer than I have professionally.”

Onscreen Rivera’s love life is also heating up. Demi Lovato has joined the cast of Glee as Santana’s new girlfriend!

“I’m very, very excited about it,” Rivera revealed of her character’s new storyline.
