We hope these celebs have their frequent flyer cards ready. Celebuzz is keeping track of the tons of Hollywood stars that are across the pond to promote their latest endeavors.

From international film festivals to European premieres, the stars were heavy on the travelling in today’s edition of Celeb Snaps.

Where did the stars get spotted?

Kristen Stewart, 22, arrived in Paris at the Charles de Gaulle International Airport looking uncharacteristically cheerful. The Twilight actress is the face of the Balenciaga’s fragrance, Florabotanica, is expected to sit front row during their Paris Fashion Week show on Thursday, Sept. 27.

A librarian-chic Emma Watson,22, was spotted leaving BBC Radio 1 in London on Tuesday after promoting her film The Perks of Being a Wallflower.

The Harry Potter actress revealed that she can’t watch certain parts of the new film: “When I watch the film back, there are a few things I can’t watch. I can’t watch the Rocky Horror dancing scene, and I can’t wait the kissing scenes.”

Back in the States, Justin Timberlake, 31, — fresh off of his bachelor weekend in Mexico — hit the green at the 2012 Ryder Cup Captains & Celebrity Scramble in Medinah, Ill. His gorgeous fiancé, Jessica Biel, 30, was on hand to support her soon-to-be husband play.
