LeAnn Rimes wishes engaged ex Dean Sheremet all the best on Twitter

Things may have not ended well (at all) for LeAnn Rimes and Dean Sheremet, but country singer's ex is moving on -- and if casual 140-character public declarations are to be taken at face value, she couldn't be happier for him.

Rimes tweeted a congrats to Sheremet and his new fiance Sarah Silver on Nov. 13. "Congrats to @deansheremet and @sarah_silver on your engagement," she writes. "A little birdie told me the happy news last night. Wishes for a life full of happiness."
