Simon Cowell admitted his incident with a Beverly Hills cop last week was "slightly embarrassing" -- but we already knew that, 'cause when we brought it up last night, his face instantly turned bright, bright red!

Simon was out at Beso for dinner with ex-GF Terri Seymour last night -- but they left in separate cars.

Just friends?
