2012 Olympic gold medalists Gabby Douglas and Missy Franklin visit 'The Tonight Show'

Douglas will appear on Monday, Aug. 13; Franklin set to visit on Wednesday, Aug. 15

Newly crowned Olympic champions Gabby Douglas and Missy Franklin will make their first late-night appearances since competing in the 2012 London Olympic Games when they visit "The Tonight Show with Jay Leno" (weeknights, 11:35 p.m. on NBC) on Aug. 13 and Aug. 15, respectively.

Gymnast Douglas, winner of two gold medals in London, became the third consecutive American gymnast to win the all-around competition. Swimmer Franklin, winner of four gold medals and one bronze medal, set one individual world record and was a part of the 4x100m medley world-record relay team.

Both athletes will be making their "Tonight Show" debuts. Douglas will join first lady Michelle Obama, who recently led the U.S. Olympic delegation for the 2012 Summer Olympic Games, and Franklin will join Sylvester Stallone.
