Zac Efron has decided to take a break from filming and just have some fun with his girlfriend in Hawaii.

The 'We are your Friends' actor has just posted a new picture on Twitter, showing model Sami Miro in a tiny white bikini on the beach. Efron is in a white rash guard, which effectively covers up his abs. He is holding his arms up as the couple pose on the shore.

The photo caption was simply "I'm like hey what's up hello."

The actor is reportedly in Hawaii to film the comedy 'Mike and Dave Need Wedding Dates,' which will also star Anna Kendrick, Adam Devine, Anna Kendrick and Aubrey Plaza. The movie is about two crazy brothers who place an online ad to find dates for a wedding and end up with a crazier surprise.

Entertainment Tonight has also posted a Twitter picture of the couple hugging in ankle-deep water. "@ZacEfron & GF @SamiMiro bring the heat to Hawaii!" the caption said, followed by a link to more photos.

Miro and Efron were introduced by Sean Penn's daughter Dylan. The model has a degree in marketing as well as a Masters in global entrepreneurship. She has also won several California state championship medals in gymnastics.

Efron is best known for playing Troy Bolton in the 'High School Musical' film series. He has also starred in the latest film adaptation of the Broadway hit 'Hairspray' and the romantic drama 'The Lucky One.' The 27-year-old actor has made a shift to edgier roles by playing a wild frat boy in 'Neighbors.'

The actor has just finished filming 'Dirty Grandpa' opposite Robert De Niro and Zoey Deutch. Zac Efron will appear as an aspiring DJ who romances model Emily Ratajkowski in 'We are your Friends,' which will be released on August 25, 2015.
