Rapper Big Sean and Glee actress Naya Rivera
Rapper Big Sean has proposed to his actress/singer girlfriend, Naya Rivera.

Glee star Naya Rivera is preparing to walk down the aisle after rapper beau Big Sean popped the question.

The couple, who first connected on Twitter earlier this year, have been dating for just six months.

Rivera, 26, proudly showed of her new accessory at the Latina Magazine's Hollywood Hot List party.

The actress/singer teamed her square-cut diamond engagement ring with a low-cut camisole tucked into black silky trousers.

The lovebirds went public with their romance in April.

In May Big Sean recently gushed about his other half in an interview with E! News.

"Every morning I wake up, I look over at her and be like, "I'm winning so hard,"' the Hall of Fame hitmaker said.

Rivera, who has been busy promoting her debut single Sorry, which features her 25-year-old fiancé, said: "He's awesome, and I'm really happy, and I feel like I'm in a really good place in my life.

"So yeah, we're doing really well."

Big Sean was previously in a long-term relationship with high school sweetheart Ashley Marie.

Rivera has been linked to stars including Douglas Booth, as well as her Glee co-stars Mark Salling and Kevin McHale.
