Naya Riveria revealed on Thursday (Oct 4th) that she is engaged to rapper Big Sean after flashing her diamond ring on the red carpet.

The 'Glee' star was attending the latina magazine's 'Hollywood Hot list' party, where she showed of her engagement ring.

Riveria began dating Big Sean, whose real name is Sean Michael Anderson, about six months ago according to Just Jared, who first reported their engagement.

The relationship is very 21st Century as the couple met on the social media site, twitter.

The 26 year-old told Access Hollywood in September, "I had followed him and he sent me a little message like, 'I'm a fan', I tweeted that I followed him, I was trying to get his attention".

She added, "We went to dinner and the rest is history."

When asked if marriage was on the cards in the future Riveria immediately responded with "Absolutely!"

The couple first confirmed they were dating when they attended the LA movie premiere for the biographical sports film '42' back in April.

The diamond ring that Riveria showed off at the Latina Magazine "Hollywood Hot List" event at The Redbury in Hollywood "looks like a princess cut diamond surrounded with a halo setting, which is something that's been trending for the last three to four years. Natalie Portman was one of the first stars to wear this style," according to jewellery expert Michael O'Connor who was tapped by E!News.

He also said "I would estimate it's 3.5 carats to four, but closer to four carats with a platinum setting. The diamond looks to be in very good quality, of course, so her ring probably retailed at around $70,000."

Big Sean certainly to spare any expense and admitted to GQ magazine that he's "Gleekin' heavy" adding "How could you not, man, if that was your girlfriend, you'd probably be Gleekin' too."
