This was her first award show since announcing she is expecting her second child with fiance David Gardner, reported People magazine.
Gardner took to Instagram to send a sweet message of support to Tyler and HBO's "The Leftovers", which is nominated for best drama series.
"Sooooo beautiful. Good luck tonight at the Critics choice awards... Baby onboard."
Tyler, 38, reposted the picture to her own Instagram, joking about her "total nerd face".
