Zac Efron, Brittany Snow And Their Celebrity Friends Attend Haunted Hayride

Zac Efron appears to be in good spirits after his secret stint in rehab was revealed last month.

The 25-year-old actor cuddled up to friend and "Hairspray" co-star Brittany Snow as the pair attended a Haunted Hayride in Los Angeles on Oct. 10. In a photo, Efron has his arms around Snow, 27, while the duo enjoy the spooky tour.

But romance rumors are most likely false due to the fact that Snow is reportedly still dating "Teen Wolf" star Tyler Hoechlin.

Efron and Snow had a great time hanging out with their fellow celebrity friends, including Julianne Hough and her brother Derek, who posted the below photo of the group on Instagram. "Great time last night with great friends. Love this time of year," he wrote.

Efron broke his silence about his alleged drug use on his WhoSay account a few weeks ago, thanking his fans for their support. "Hey guys! Just returned from an incredible trip to Peru with my dad and wanted to thank you all for your support these past few weeks," he posted along with a photo, adding, "means the world to me. Love you guys!"
