Just last night, she spent her 22nd birthday with family, friends, and 'boyfriend' Blake Griffin.

And Kendall Jenner was all smiles as she supported Blake at one of his NBA basketball games at Staple Center in Los Angeles on Saturday. The model, 22, looked more than thrilled as she sat court-side to watch her star athlete 'beau' shoot some hoops.

Kendall wore a casual ensemble with a turtleneck sweatshirt and a pair of ripped jeans. The TV reality star added a glamorous flare with kinky knee-high boots covered in crystals, retailing at an eye-watering $10,000 at designer fashion house Saint Laurent.

The brunette-beauty kept her in a ponytail, while also sporting a natural make-up look with a red lip-color. Jenner added more shine to her casual ensemble with a pair of diamond earrings and a ring. At the game Kendall was accompanied by a friend as she gazed up at the court to support her hunky 'boyfriend' play the Memphis Grizzlies.

It's been reported Kendall and Blake have decided to move beyond the hooking up stage onto something more serious.

A source told Us Weekly: 'They're legit. They're a full-on couple.'

Kendall has been going to a lot of his games and they have been enjoying time at home when Blake is in town. They're good.

'The star's new relationship status comes just over a month since it was claimed she was enjoying 'playing the field.'

It was said she was both dabbling with with Blake while still talking to her rapper ex-boyfriend A$AP Rocky, who she enjoyed a brief affair with last year.
