Renee Zellweger has become an airport Starbucks connoisseur.

The actress travels so much and spends so much time waiting for planes she has spent a lot of time cafes, and now, even though she has given up coffee, she still picks up her green tea at Starbucks before a plane ride.

"I'm pretty up up on my Starbucks geography," she tells pal Harry Connick, Jr. during an appearance on his new TV chat show.

And she always seems to be able to sniff out a good Starbucks on her travels around the globe.

"I even went to the Starbucks inside the Forbidden City in China," she recalls. "How great is that? It's like having a Starbucks in the Statue of Liberty.

"I think it's closed now but I was excited to have had the experience."
