Birkelbach says someone literally tapped her on the shoulder and said 😛 TAGEND

“‘Just so you know, Renee Zellweger is over there cleaning kennels and doing your laundry.'”

The founder was stunned. Birkelbach told TODAY she found out Zellweger had been volunteering for hours — but no one knew because she didn’t ask for any celeb therapy:

“She had already been there for a couple of hours, altogether incognito. She was here four periods literally cleaning crates, doing laundry and strolling the dogs.”

Obviously Birkelbach constructed sure to get some snaps after she recognized!

In case you didn’t know, the Bridget Jones star is NOT from the U.K. but is in fact a native Texan who grew up in Katy.

She had already volunteered a few days with the sister organization Austin Pets Alive, as well as MAD Dog Rescue and Lucy’s Pet Foundation. After a full week, she reportedly brought eight homeless bird-dogs back home with her to find new homes in El Lay. Amazing!

Renee spoke to Houston’s local ABC1 3, explaining 😛 TAGEND

“Like everybody else out here, y’know, I’m a Texan, and I just wanted to find a place where I could contribute. I heard that a lot of Houston dogs were being sending them to shelters in San Antonio, and in Austin to make room for some of the strays the latter are observing with be available to reunite dogs with their families, so I kinda knew where I was goin’. I volunteered at the Town Lake Shelter when I was in college in Austin … This was familiar to me.”
