Loved-up Zac Efron celebrates his anniversary in the SWEETEST way

Zac Efron and Sami Miro have never been overly public about their relationship on social media, but after a year together they've finally opened up.

The couple each posted seriously lovely-dovey Instagram statuses yesterday in honour of their first anniversary, which took place on September 5th.

Zac's been on a hectic promotional tour for his new film We Are Your Friends over the last month, but he was finally reunited with his girlfriend this week and wasted no time in telling the world how much he adored her.

"Happy anniversary baby 🙂 I love you @samimiro September 5th," he wrote, posting a picture of the pair kissing in silhouette. 

Sami also shared an equally smitten Instagram update in response, posting a selfie of herself and her man with the caption, "Time flies when you're having fun. Happy anniversary baby I love you too @zacefron September 5."

How cute are these two?!

Zac and Sami were first pictured together this time last year, just weeks after his short-lived fling with actress Michelle Rodriguez ended.

However they only made their first official red carpet appearance as a couple last month, at the LA premiere of We Are Your Friends.

Sami looked every bit the Hollywood glamour queen at the August 20th event, weering a sheer minidress with silver lace overlay, accessorised with a white coat and a metallic clutch.

Zac has always gone for women who stand out from the crowd, a friend told People shortly after he made things official with Sami. The actor apparently likes "outspoken, independent women who challenge him."

We reckon this pair have serious staying power.
