Selma Blair's son Arthur debuted a dramatic new look as he posed with his actress mom for rare snaps this week.

Arthur, 13, whose dad is Selma's ex Jason Bleick, 53, sported a bleach blond buzzcut - matching Selma's hair color as they posed for a mirror selfie.

Selma captioned the snap: 'Has my son surpassed by 5ft 4?' as Arthur did the rocker sign next to her.

The pair also posed for another sweet selfie later in the day. 

The Legally Blonde star and Arthur's fashion designer father, Jason, dated from 2010 until 2012. The pair welcomed Arthur in 2011.

Blair has candidly discussed the 'very hard' start to motherhood she faced amid her MS diagnosis, and said she went from 'blissful pregnancy to utter devastation' after giving birth.

Reflecting on the tough period of her life with Glamour Magazine, she said: 'The MS flared very obviously, when I was in labor. My body started going through distress as bodies can, and, of course, I didn't know I had it.

'And so the moment Arthur was born, I went from this kind of blissful pregnancy to utter devastation.'

Blair added: 'Everything was too overwhelming. I couldn't be in a relationship. There was nothing I could do except be a mother. And I was brutally tired and I didn't have a support system. I didn't know how to set one up.'

'So even though I'm sociable and friendly, I'm alone for everything. And this child automatically became my biggest responsibility, my biggest love, but it was a very, very hard adjustment for me. Very hard.'

When she was diagnosed with multiple sclerosis at age 46, it was a relief - it explained the physical pain and neurological symptoms she had experienced since childhood.

She previously revealed that she and Jason have a 'flexible' custodial and co-parenting arrangement, which has been helpful since her MS diagnosis.

'Jason is a huge part of Arthur's life. He's shown up in a big way,' she told People in 2019. 'I'm really proud of us.'

In 2022 during a tearful interview on The Drew Barrymore Show Blair shared that she never felt hope until Arthur was born.

Speaking of her traumatic childhood, as well a trauma of sexual abuse and alcohol addiction, she explained, 'I didn't know I had hope until I saw my son, and I love him more than anything. and I think, "My God, if he started drinking right now, or if he started doing the hurtful things to girls that people did to me, what would I do in loving to get him on track?"'

'We love our kids the most, and we realize we want nothing to get in the way of that,' she added.

Earlier this month Selma gave an update on her health during the 2023 Glamour Women of the Year Awards.

She spoke to Entertainment Tonight at the star-studded event and revealed that she had been making much progress since her diagnosis. 

The performer also spoke about being in remission and adjusting to life with the condition. Blair began by revealing that, although 'it took a while' for her to recover from multiple sclerosis, she was 'feeling really, really much stronger now and building stamina.'
