When they swanned to the red carpet at The Hangover: Part III premiere in Westwood, California, on Monday, Naya Rivera's rapper boyfriend placed a hand protectively around her waist.

And as the Glee star was baring an impossibly trim and toned midsection, it wasn't hard to see why Big Sean wanted everyone to know that she was his.

The 26-year-old actress looked positively radiant as she hit the red carpet with her boyfriend at her side.

The hot couple: Naya Rivera showed off her tiny waistline next to rapper boyfriend Big Sean, who's rapped about his love of small waists, at the Monday premiere of The Hangover III

A black bandeau top left the star's upper abs on full display as her tight, knee-length skirt covered her stomach to just above her belly button.

Obviously feeling confident in her black and sequined ensemble, Naya couldn't stop smiling.

Known for playing sharp-tongued former cheerleader Santana in Glee, the star is used to maintaining such an enviable figure.

She once shared with FitSugar that her trick to staying trim includes lots of squats and planks.

Her workouts certainly paid off as she presented a sleek, slender and healthy-looking figure on Monday.

Naya's long brown locks were half tied up in braids, letting the remainder of her hair cascade down her back and shoulders.

Her 25-year-old beau showed off his own buff physique in a grey button-down tank top, and accessorised with a single, understated gold chain and matching watch.

The pair have been publicly dating since only April, but they seem to be brimming with happiness.

Naya opened up to E! Online about the relationship recently, saying: '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.'
