Following his stint in rehab it looks like Zac Efron has decided to add former girlfriend Lily Collins to his support system seeing as Vanessa Hudgens is too busy with her boyfriend Austin Butler.

Efron, 26, has started to spend time with his former flame Collins, 24, and it seems the actress has been doing her best to help the actor stay healthy.

The "That Awkward Moment" star is getting help from "The Mortal Instruments: City of Bones" actress as he adjusts to a new way of living after his stay in rehab due to alcohol and drug abuse, according to Hollywood Life.

Lily Collins and Zac Efron have known each other for quite some time and according to sources the actress does not drink or do drugs and has been helping Efron maintain a substance free lifestyle.

According to an insider, Collins is very positive and an inspirational personality. The source said, "Lily is the perfect girl for Zac to be dating right now. She's young, gorgeous and smart - but more than anything, she doesn't drink or use drugs.

"Zac knows if he wants to save his career and his life, he needs to stay sober and it's making his transition a lot easier to be dating someone like Lily."

The two seem to be having fun together as they were recently spotted holding hands while at Disneyland on October 22nd.

Although, several days before Zac Efron was seen cuddling former "Hairspray" costar Brittany Snow it is clear that he has made his choice to see where things go with Lily Collins.
