LOL! Jesse Tyler Ferguson might be the best costar ever. The Modern Family actor posted a hilarious picture of cast mate Sofia Vergara while on set filming in Los Angeles to his Instagram on Friday, Aug. 8.

In the pic, Vergara looks like a seriously disheveled hot mess. Wearing baggy sweats and Croc sandals, the usually glam Columbian looked distraught while in character with red lipstick all over her mouth and unruly hair. "#IWokeUpLikeThis," the funnyman captioned the image.

The actor then shared a video from on set where he and Eric Stonestreet pretend to make out with cardboard cutouts of themselves with the caption, "Leave us alone."

Off set, Vergara and Ferguson recently supported fellow cast mate Sarah Hyland, who performed in Hair at the Hollywood Bowl on Aug. 2, with their better halves Joe Manganiello and Justin Mikita.

"The @therealsarahhyland fam crew for Hair at the Hollywood Bowl!," Ferguson captioned the selfie, in which Vergara looked more like her usual self!
