Katherine enjoyed a short vacation at the picturesque Las Ventanas al Paraiso resort in Los Cabos, Mexico, last week, posting pictures on her social media pages from the trip. "Enjoying a girls weekend in Mexico!!! Sun, sea and margaritas!" she told followers, sharing a poolside photo with her sister Meg at their coastal location.

Staff at the venue prepared a surprise greeting on the beach for Katherine, Meg and mom Nancy, as they headed out to enjoy an alfresco dinner on Monday night. The trio stopped to pose for a photo behind the artistic creation which welcomed them to their table.

Yesterday evening, following her return from Mexico, Katherine attended the premiere of Warner Bros. Pictures and Legendary Pictures "42" at the TLC Chinese Theatre in Hollywood. She was there lending her support to former Grey's Anatomy co-stars T.R Knight and James Pickens Jr. both of whom have roles in the movie.

The picture tells the life story of Jackie Robinson and his history-making signing with the Brooklyn Dodgers which broke baseball's color barrier. Katherine was also joined by other Grey's alumni at the event and after party, including Justin Chambers and Kim Raver.
