Whitney Houston Funeral Costner, Davis Among Those Paying Their Respects

Whitney Houston's "Bodyguard" co-star Kevin Costner and mentor Clive Davis were among those who gave touching speeches during her funeral service this afternoon.

Whitney's cousin, Dionne Warwick, also gave a moving tribute.

While Houston's service was moving, it wasn't without some controversy. Bobby Brown left the service after just a short time after a disagreement with Whitney's family. We're told they objected to Bobby bringing a nine-person entourage with him.

Alicia Keys, R. Kelly and Stevie Wonder were among the performers who sung in Whitney's honor.

RIP Whitney.
