The 'Clueless' actress' was emotional when nine-year-old Bear - who she has with ex-husband Christopher Jarecki - decided he wanted to "try something new" with his locks but she's very supportive of his decision, though she has a "feeling" he'll decide to let his tresses grow again.

She shared a video of Bear getting his hair cut on Instagram and wrote: "Yes, It’s true. Bear cut his hair!! My baby’s growing up.

“I miss his hair!!!!! Was it his decision? Yes. Did I cry inside as I watched him get it cut? Maybe… but did I try to stop him? Not for one second. The reason he chose to keep it for as long as he did was because he loved it so much!!! He just wanted to try something new.

"Although I have a feeling he’ll find a way back to his long hair again in the future.

"No matter what though, I will always support my sweet, caring, and precious little boy in every decision he makes.(sic)"

In the clip, Bear admitted he was "nervous" about making the change.

Alicia asked him: "What are we doing right now?”

He replied: "Cutting my hair."

When she asked him why, he replied with a smile: “I have no idea."

She then asked if he was nervous at all, and Bear admitted: "Yes, very."

But the youngster also said he felt "so excited" as two stylists worked on his hair.

Bear's haircut came two months after the 44-year-old actress revealed her son had been bullied because of his flowing tresses.

She wrote on Instagram: "One time my son was made fun of by other kids because of his hair on a bus ride to surf camp.

"After he had returned and told me, I thought he would want to cut it for a haircut appointment we had already scheduled the next day, but when we showed up, he said "please give me a trim so I can grow it to my waist."

"That's my boy! He knows who he is. He loves his hair and chooses to have it long. Mama and Papa aren't going to stop him from being him. He's beautiful and we love his hair! (sic)"
