Fotonoticias/Getty ImagesAfter sounding off on her dad on Twitter Friday, Miley Cyrus headed back to the social networking site to send him a sweeter tweet.
"Happy Daddy Day @billyraycyrus," the "We Can't Stop" crooner wrote Sunday, ending the message with a heart-shaped emoticon.
After Billy Ray Cyrus filed for divorce from Tish Cyrus Thursday after more than 19 years of marriage, Miley appeared to be having difficulty getting in touch with her dad.
"@billyraycyrus since your text and email obviously aren't working would you like to talk like this?," she tweeted (and later deleted) Friday.
Billy Ray's filing marks the second time he filed for divorce from Tish. The "Achy Breaky Heart" singer first filed in Oct. 2010, but later withdrew the filing in March 2011 after an apparent reconciliation.
