EVENT : The 12th Annual Day Of The Child Event+Ron Artest's Official Birthday Celebration

Many of our celebs like Kenny Lattimore, Forest Whitaker and Gabrielle Union were out in LA yesterday raising money for a good cause. See pics inside plus photos from Ron Artest's birthday party in LA.

Children Uniting Nations 12th Annual Day Of The Child Event was held at the Star Eco Station in Los Angeles, CA yesterday.

It may be the holiday season but Gabrielle Union looked like she was ready for a summer picnic. Still cute.

She even took some time to pose for the kids.

And kicked it with Daphna Edwards Ziman and Adrian Grenier.

Oh hey Forest Whitaker.

Forest Whitaker and his wife Keisha hit the carpet with their kids:

Heavy D also hit the event. Where you been Diddly D?

As did Reggie Miller......in that shirt. SMDH.

Cutie Kenny Lattimore was there.

Inside, Kenny Lattimore hung out with Abraham McDonald and Kenneth Crouch.

And later that night, many celebs went to the Conga Room at L.A. Live for Ron Artest's bday.

Funny lady Luenell was there.

Ron Ron partied it up of course.

Laker baller Matt Barnes came out to support his teammate.

I wonder if he rapped some of his songs.

And Faith Evans hit the mic.

Actor David Arquette went a little overboard with his Laker Love.

I guess we know who David wants to see in the finals.

Ron took a group shot with all the lovely ladies, stylist Gina Everett, Luenell, wife Kimsha Hatfield, Faith Evans and Antonique Smith.

At the end of the night, Ron got on stage to thank his guests along with his wife Kimsha Hatfield. Sweet.
