It's a children's film Bella! Thorne grinds against bashful Alvin The Chipmunk at premiere of family friendly movie

It was the premiere of the family friendly film, Alvin And The Chipmunks: The Road Chip.

But that didn't stop Bella Thorne from getting up close and personal with Alvin himself on the red carpet.

The 18-year-old seemed to catch the mascot by surprise as she playfully cosied up to him in Los Angeles on Saturday.

For as surprised as Alvin initially appeared to be by Bella's bold move, it seems the chipmunk also fell under her spell.

During another group photo, Alvin pulled Bella in for a squeeze.

Still, Bella looked every bit the professional as she flashed a wide and playful grin beside Alvin and his brothers Simon and Theodore Seville.

As per usual, Bella looked incredible on both the fashion and beauty front.   

The rising star had her fiery red hair styled in glossy loose ringlets and she polished off her face with a slick of strawberry pink lipstick and mascara. 

Bella glammed up the look with a silver clutch, gold bracelet, and a pair of suede red heels.

In Alvin And The Chipmunk: The Road Chip, Alvin and his brothers travel to Miami with their potential future stepbrother in order to stop Dave (Jason Lee) from proposing to his girlfriend, Shira (Kimberly Williams-Paisley).

Aside from the film, which is scheduled for release in the U.S. on December 18, Bella has been dating actor Gregg Sulkin, 23.

In a recent interview with Seventeen magazine, Bella discussed her romance with Gregg, and also about a relationship she had with a previous jealous ex-boyfriend.

'An ex of mine and I knew each other's phone passwords, and he was constantly going through my phone. I learned not to do that because anything can be misread,' she said.

'Gregg has my password, but he doesn't go through my phone. The ex and I also plays a "Don't talk to the opposite sex" rule, so if a guy I was working with wrote me, it would be a big problem.'
