It's the most romantic day of the year, with couples celebrating their love for each other at overpriced restaurants surrounded by other equally smitten pairs.

So John Mayer took Katy Perry out for Valentine's Day on Thursday night, the singer decided to dress to impress for the evening out.

The 28-year-old star wore a pretty cream and red patterned vintage full-length gown as the pair headed for a bite to eat at The Cut restaurant in Brentwood, California.

Katy wore a cream ribbon around her middle to highlight her tiny waist, and teamed the dress with a pair of black heels, and a matching black handbag.

The Wide Awake singer finished off her ensemble by wearing her raven black hair in loose waves, and accessorised with gold jewellery.

And it seems as though it was a successful first Valentine's Day for the pair, as Katy beamed while leaving the restaurant clutching a Fred Segal bag which appeared to be full of presents.

What a gent: Gallant John made sure he held the door open for his girlfriend, who beamed as she carried a bag believed to contain her Valentine's Day presents

However, while his stunning girlfriend dressed up for the occasion, John went for a typically eccentric look - teaming his smart grey trousers with a casual denim jacket and colorful striped scarf.

The 35-year-old finished off his ensemble with a tan bag worn across his body.

And it's been a busy week for the pair, who were also spotted enjoying a pre-Valentine's Day dinner on Tuesday night at Katsuya in Brentwood.

The holiday marks John and Katy's first Valentine's together, but seems to be setting a precedent for a lot more to come.

Acc! ording to! reports, the couple, who have been dating on and off since Katy's divorce from Russell Brand, are going from strength to strength - especially after John hit it off with Katy's parents.

A source said: 'Katy has never been happier. Shes in a really good place with John. Katys parents also really like John. They prefer him over Russell.

'They thought Russell was too temperamental.'
