Lea Michele has said she is feeling "revived and refreshed" after a New Year's holiday.

The Glee star had a tough time in 2013 as a result of the loss of her co-star and real-life love Cory Monteith, but told fans on Twitter that she's feeling good after unwinding in Mexico with her best friend, Frozen actor Jonathan Groff.

She tweeted: "Such a lovely holiday break with friends and family. Revived and refreshed:) Ready for this new year!"

During her break, Lea, 27, shared several images of Mexico and of her and Jonathan swimming and enjoying the sunshine.

She also posted a revealing snap of herself with her back to the camera, wearing a skimpy bikini. It was captioned: " What an amazing week in Mexico... New day. New year. #Bringit2014."

On New Year's Eve, Lea thanked fans for their support after Cory died from an accidental overdose in July.

" Wishing everyone a very happy new year.. Sending much love.. So grateful to all of you for all your endless love and support this year," she said.
