As if Live! With Kelly and Michael needed any more excitement.

Pretty Little Liars star Shay Mitchell filled in for Kelly Ripa during Monday's show -- Ripa has been MIA since Michael Strahan announced last Tuesday that he was leaving the show -- and suffered a wardrobe malfunction on air.

"A little #commercialbreak sewing after a wardrobe malfunction. No biggie," the official Live! account posted alongside a video of the quick fix.

The 29-year-old actress shared her own photo and wrote, "AS IF I WASN'T NERVOUS ENOUGH... casual wardrobe malfunction while co-hosting @kellyandmichael...Thank you @michaelstrahan , I had THE BEST time!"

Ripa is set to return to the talk show on Tuesday, a week after sources told ET she felt "betrayed" and "blindsided" by the news of Strahan's departure. On Friday, she wrote a letter to Live! staff, thanking them for "giving me the time to process this new information."

Meanwhile, Strahan says he is "excited" for Ripa's return. Watch in the video below.
