Selma Blair and her baby daddy Jason Bleick have called it quits, according to Us.

The Anger Management starlet, 40, began dating her fashion designer boyfriend back in 2010 while she was collaborating on his EVER fashion line.

Blair gave birth to their son, Arthur, in July 2011. The mother of one was previously married to Ahmet Zappa from 2004 - 2006.

We've reached out to Blair's rep for comment, but have yet to hear back.
