She’s had a difficult year following her split from fashion designer, and the father of her child, Jason Bleick.
And it seems that Selma Blair is feeling the strain following a tough few months, the results of which has led to drastic weight loss.
The 40-year-old actress displayed her shockingly thin, almost-skeletal figure as she took her son Arthur to the park in Laurel Canyon, Los Angeles.

As she ran along pushing her little boy in his toy car, Selma’s baggy knitted cardigan fell open – displaying her incredibly bony chestplate.
The Anger Management actress, who went bra-less and narrowly avoided a wardrobe malfunction on the energetic morning out, also looked extremely tired – her make-up free complexion only serving to draw attention to the heavy bags under her eyes.
Despite Selma’s clear stress, the actress did her best to concentrate on spending time with her 16-month-old son.

Arthur looked adorable in a striped all-in-one, with a gilet and hat over the top to keep him warm.
And the little boy certainly appeared to be enjoying himself, beaming and giggling with delight as he explored the local area.
Selma gave her son a hand as he waded through the sticks and twigs in the local area, keeping a close eye on Arthur as he toddled off exploring.
The actress is doing her best to move on, following her split from Jason in August – just 14 months after they welcomed Arthur into the world.
The actress and her fashion designer partner, who had been dating since 2010 were alleged to have parted ways because they couldn’t stop arguing.
A source told Us Weekly magazine: ‘They were fighting non-stop.’
Selma rather vaguely commented on her relationship status in September on Twitter, writing: ‘I never announced anything. They choose to write whatever they feel. I do not have a new boyfriend. My son is it.’
