The on-again, off-again nature of Katy Perry and John Mayer's relationship is officially making me dizzy. The sometimes couple was spotted out to dinner recently in L.A. with another couple and "definitely" looked like they were together, a source tells E! News. They were apparently packing on the PDAs, "acting cozy" and holding hands throughout dinner, which must've made eating awfully cumbersome, but whatever.

The flighty and indecisive couple was last spotted acting suspiciously friendly at a party in January, so maybe they're just on a strict quarterly dating schedule?
