Almost every celebrity move has a strategy behind it, and that's been true throughout time. Cultivating a public image takes a little bit of calculating, say what you will of it.
That's why when a celebrity says something publicly, it means something. Sometimes, it just means promo for a new project, but once in a while, there's something that cuts deeper.
Here are just some of the many times celebrities really came for each other.

2.Elton John and Madonna were sort of friendly before he chewed her out at the 2004 Q Awards.

4.But Mariah is always locked, loaded, and ready to fire, as evidenced by her feud with Eminem.
5.Kevin Smith's disdain for Bruce Willis makes for some surprisingly juicy Hollywood drama.
Smith never shied away from his feelings about Willis after that.
