Grey's Stars Katherine Heigl, TR Knight in Paris
"Grey's Anatomy" star Katherine Heigl and her good buddy and co-star T.R.Knight who played this season's most infamous couple on television have just returned from Paris, France where Heigl continued promotion of her recent comedy "27 Dresses."
Heigl, who came to Knight's defense during the Isaiah Washington incident last year, met up with her pal after traveling for 10 days across Europe with her parents.
A boyfriend-less Knight also used the opportunity to explore one of the most romantic cities in the world on his own.
Both stars returned to LAX on Wednesday and are due on the "Grey's Anatomy" set in early March, when production on the final 5 episodes of their hit drama's 4th season begins.
