She completed the look with a black beanie and some circular sunglasses.

The Teen Wolf star couldn't help but gaze at his flame-haired girlfriend.

He wore a similarly casual ensemble consisting of knee-length shorts and a dark t-shirt.

The 24-year-old star tenderly placed his hand on the Blended star's back as they joined some other pals for the lunch outing.

Do skater girl cool in a Thrasher tee

Ah, young love. When you start matching with your beau you know it's meant to be. Adorable. Bella Thorne and Tyler Posey are certainly an item as they're both rocking skater-approved tees together. That's pretty cute.

This tee is classic on the skate scene, an offshoot of Thrasher Magazine, the bible for wannabe Tony Hawks and Chad Muskas everywhere. So girls, or boys, if you're in need of a style overhaul then why not channel this Californian cool look?

Click (right) to buy a similar version and wear with baggy jeans and trainers for some tomboy style. Or go for that indie cool girl look like Bella and make it into a long shirt dress and just add some funky snakeskin boots. Of course it helps if you know your way around a skateboard so if you don't want to fake it then check out the other tees in our edit below.

Earlier Bella wore a white bikini as she nuzzled up next to Posey, who was wearing swim trunks for some poolside fun. 

The couple was seen on Snacpchat joining Bella's older sister Dani, 23, as a large inflatable pink flamingo could be seen in the background for the antics.

Tyler also shared a photo of the twosome in bed, as he regaled her with more sweet nothings for her special day.

'I love these women,' the Santa Monica native said in an Instagram shot alongside Bella and his dog Roxy. 'My red haired beauties. Happy birthday my love @bellathorne sorry I was a couple hours late, I was too distracted by your face.'

The young Hollywood couple initially emerged a few weeks back when they were spotted engaging in PDA in West Hollywood.

Tyler two years ago ended an engagement to makeup artist Seana Gorlick after 10 years together.

Bella and English actor Gregg Sulkin, 24, parted ways this past summer after a year together.

In a joint statement, the duo said, 'After much thought and soul-searching, we have made the difficult decision to end our relationship. We will always love each other and have a deep respect for one another, as we have each grown to be better people because of our time together.

'Our schedules made seeing each other difficult, and we decided that for now this would be best.'

Bella added via Twitter that 'things just didn't end up working the way we had hoped,' adding she'd 'always love' the Faking It star.

It's been a time of change and growth for the one-time Disney star, who celebrated entering the last year of her teens Saturday by getting her nose pierced at the Los Angeles establishment Body Electric Tattoo and Piercing.

The social media-savvy stunner shared the seemingly-painful process with her Snapchat followers, at one point, bellowing, 'Oh my God!' as the inside of her nose was penetrated with a needle.

Another checkpoint in her coming of age occurred in late August, when she revealed to her nearly 6.5 million Twitter followers that she's bisexual. Moved by the show of support over her admission, Bella tweeted, 'Aww thank you all for the accepting tweets from everyone. I love you guys. #pride,' adding three heart emojis to the message.
