He teamed it with blue shorts, which the Cruel Intentions star said were designed by Catimini Kazakhstan.

Arthur - who is also the son of Selma's ex Jason Bleick - looks to be pouting but is actually sipping on broth - as his mother noted.

Selma is hovering over her son's shoulder to take the selfie of the two while sitting on a cement ground.

Step out in style with these Vans Hi Top sneakers

We almost didn't recognize Selma Blair when she was spotted running errands in LA with her son, Arthur. Clad in a Vans t-shirt and hi-top sneakers, straight leg jeans and dark shades, the Cruel Intentions star played it super low key.

Selma seems to be a fan of the California based brand and with good reason. The casual slip on trainers were once only highly favored by skater boys and girls, but now Hollywood has taken notice with Sofia Richie, Jenna Dewan Tatum and Kristen Stewart wearing their sneaks all around town.
