Counters a Richards pal: "It is 100 percent true." (Math, Hollywood style.)
This much is certain: On May 20, Locklear, 44, joined pals, including rumored beau David Spade (who sources say is just a friend), for dinner at L.A. hot spot Republic.
That same night, Richards, 35 – who is now seeking a cut of Charlie Sheen's Screen Actors Guild pension in addition to sole custody of their two kids – watched from backstage as Sambora, 46, rocked out with Bon Jovi in Dublin.
The two then hopped a private jet and checked into a five-star hotel south of Naples.
Who needs drive-by serenades? They can make their own music.
