Two-time Academy Award winner Meryl Streep has kissed a lot of lips throughout her celebrated career but when she visited The Ellen DeGeneres Show Thursday the acting maven couldn’t discern whose lips were whose when Ellen flashed photos of her costars on the screen. In fact, when presented with her second pair of female lips in the game Meryl had a tough time recalling whose they could possibly be.

As Meryl stared at the photo going through her mental Rolodex, Ellen asked, “How many women have you kissed?”

“I can’t remember how many women,” Meryl replied.

Golden Globe nominee for The Iron Lady Meryl has played lesbian in Woody Allen’s 1978 film Manhattan and in the 2002 film The Hours, in which Alison Janney played her partner. But Meryl has had a few more ladies in her life than merely in those two films.
