Katy Perry noticed Robin Thicke sitting in front of her and reached out to toast the Blurred Lines singer during Ringo Starr's performance.

Both pop stars were drinking out of plastic cups - though the cups weren't quite as glamorous as the new "sippy cup" Jay-Z joked that he acquired for his daughter Blue as he accepted the Grammy for best rap/sung collaboration for "Holy Grail."

No alcohol was sold inside the Staples Center lobby before the show.
