Zac Efron is styled by his girlfriend.

Sami Miró has revealed the pair regularly go on shopping sprees together where she picks out outfits for the '17 Again' star to wear.

She said: ''So I think with Zac - we shop together all the time, and I just naturally like to pick out clothes - our styles have mixed together.

''I definitely do borrow some cool shirts and jackets of his, too, so it works out really well. We kind of coordinate in a way.''

The model also admitted she finds it ''different'' dating the Hollywood hunk and has changed how she uses social media, particularly Instagram, now the pair are an item.

She told ELLE.com: ''I've never spoken about us before, but, um, it's definitely different. I think that you have to take that [kind of attention] with a grain of salt... It kind of just comes with the territory, and I know there's no really changing that, so you have to just embrace it...

''I'm not trying to hide anything in my life. If I was dating someone who wasn't in the limelight, I might have more photos on [Instagram] of our relationship, but I do think it's important. I mean, it's what is going on in my life, and I think that my social media can still represent that.''
