He was covered in thick green slime while hosting Kids’ Choice Awards on Saturday night.

But John Cena cut a dapper appearance as he smartened up to whisk his fiancée Nikki Bella off for a romantic dinner following the action-packed award ceremony in Los Angeles.

The actor, 40, headed to celeb hotspot Craig’s with the brunette beauty, 34, who looked incredible in a striking red dress.

Nikki wowed in the knee-length dress which clung to her gym-honed figure, while teasing a peek of her cleavage with its low-scoop neckline. The American wrestler styled her glossy raven tresses in Hollywood curls and accentuated her sun-kissed complexion with a brown-smoky eye, bronzed cheeks and a deep pink lip.

Meanwhile, John looked handsome in a black pin-stripe suit and peach tie for the date.

The retired wrestler had many costume changes throughout the evening, with one outfit celebrating another legend in his industry.

Wearing a grey wig and frames, John rocked a tight T-shirt with the saying, ‘I love Dwayne Johnson’ across the front.

The loved-up duo previously postponed their wedding plans, and John admitted he doesn’t know when the big day will eventually arrive.

He  said on the Ellen DeGeneres show: ‘I was able to let Nicole plan the bachelorette party and she just finished that. And now I’m just kind of on standby to know when it is and where it is, and I’ll be there.’

John also revealed that he’ll be preparing for his wedding day by learning to dance.

He shared: ‘I am super excited and I’m going to have to learn a dance.’

John – whose first marriage to Elizabeth Huberdeau lasted from 2009 until 2012 – has been dating Nikki since 2012 and the high-profile couple became engaged in April last year.
