On Saturday, Brooklyn Beckham and his girlfriend Chloë Moretz celebrated the actress' 21st birthday in Los Angeles after almost a month apart.

The 18-year-old photography student was spotted walking with his girlfriend to the birthday party, wearing smudged black eyeliner, pinstripe suit trousers and green braces.

Meanwhile, his leading lady wore a champagne-coloured Prada two-piece, adorned with feathers at the cuffs and hemline. She teamed the vintage look with soft blonde curls.

The couple kicked off the Kick Ass star's birthday celebrations at a pool party with friends earlier in the day, before donning their glad rags for the evening's festivities in a private area of a restaurant.

She captioned the snaps: 'Last night I had the most wonderful time celebrating my 21st birthday with the most special beautiful humans. Thank you so much @beautyessexla for putting it all together and making my 21st birthday dreams come true :)'

At one point during the star's party, it appears she changed out of her Prada number and into a high-neck black shift dress with knee-high lace-up PVC boots.

A bright red lip and smokey eye complimented the look perfectly.

In one Instagram post from the actress, Chloë's guests - including actress Sasha Lane - can be seen at dinner with a pillow-tiered cake at one end of the table in front of a row of inflatable balloons that spelled out 'Chloe' on one wall.

Brooklyn's grungy look comes months after he debuted jet-black dyed hair ahead of his first day at university.

In December, Brooklyn's mother Victoria joked about Chloë's influence on her son looking increasingly like Dennis The Menace.

Chloë and Brooklyn first sparked rumours of a romance in April 2016.

Following an on/off long-distance relationship, the pair rekindled their romance last year ahead of the 18-year-old's move Stateside.

Happy birthday, Chloë!
