After taking an unlucky spill outside his Hollywood home and breaking his jaw, Zac Efron is being nursed back to health by his new girlfriend Lily Collins, Breaking Celebrity News is exclusively reporting.

Collins, 24, has remained steadfast by Efron's side during his recovery -- even making him smoothies and things he can eat through a straw since his jaw is wired shut.

"Zac is so grateful for Lily. She's being so sweet with him and is going above and beyond to take care of him," the insider told Breaking Celebrity News.

"She makes him healthy smoothies he can drink through the wire and she's really good emotional support for him right now."

In fact, Collins was spotted at Gelson's grocery store earlier this week picking out fresh fruits and veggies to mix up liquid goodness for Efron, 26.

As Breaking Celebrity News previously reported, Efron completed two stints in rehab earlier this year for a struggle with alcohol and the prescription drug, Oxycodone.
