Zac Efron's Girlfriend Sami Miro Displays Slim Frame While On Hike With 'Bad Neighbors' Actor; Couple Brings Pet Dog During Stroll

Zac Efron and girlfriend Sami Miro were snapped while hiking with their dog in Griffith Park on Sunday during which time the model showed off her slim frame.

"Zac wore bright red compression leggings under his grey shorts for the walk in Griffith Park, along with black socks and trainers," Daily Mail reported. "The actor also sported a white T-shirt, and protected his face from the sun with a baseball cap and sunglasses."

The 27-year-old actor has been filming in Marrietta, Georgia for his movie with Robert de Niro titled "Dirty Grandpa."

Also starring in the movie is Aubrey Plaza of "Parks and Recreation" and Adam Pally of "The Mindy Project."

"Dirty Grandpa" is "a comedy about an uptight twenty-something (Efron) who embarks on a road trip before his wedding to bond with his recently widowed grandfather (De Niro) only to find that his grandpa is a foul-mouthed lunatic on a mission to get laid during Spring Break," said Deadline.

Earlier this month, it was rumored that Zac Efron and girlfriend Sami Miro had split after the actor was spotted on what appeared to be a dinner date with a mystery woman. But Daily Mail said that there's no hint of romance on the date.

"Zac and the mystery woman ate at Pimai It's Thai, sitting across from each other at a window-side table," the report said. "While the two diners were smiling and chatting throughout their meal, there was no particular closeness, indicating that Zac and the lady were friends or colleagues."

The Zac Efron dating Sam Miro reports began when they were spotted at the Dodgers vs. Giants game at the Dodgers Stadium in Los Angeles on Sep. 22.

Then they were snapped again in Copenhagen, Denmark on Oct. 11 when they coordinated their look with aviator sunglasses and black sweatshirts. The actor had just come off a split from Michelle Rodriguez.
