WEIRD: Why Was Kelly Rolland Crying After Her Birthday Lunch With Friend, Beyonce Knowles?

Its still not clear why Kelly Rolland was weeping after a lunch with Beyonce to mark Kelly's birthday.

The singer was seen in floods of tears outside Gjelina Restaurant on trendy Abbott Kinney Boulevard in the Venice area after her birthday lunch date with best friend and superstar Beyonce Knowles, her rapper husband Jay-Z and sister Solange Knowles...it's unclear what caused the upset, but Kelly suddenly appeared overwhelmed by her emotions as sobbed away in the street in LA.

Could it be that she was so nervous and overwhelmed to see Beyonce Knowles, who was once her mate and close friend at the defunct Destiny's Child Music Group, being so successful and popular with a loving and popular husband, Jay Z, while she is still single and nowhere to be found in the stardom chart?

Anyway, that's what life offers- sometimes it takes more than being good, it takes the grace of God!
