John Mayer And Ke$ha Spark A Twittermance

'Dear Ke$ha, you have won me over with your tricks and charms,' Mayer tweets.

John Mayer once had a Twittermance with Demi Lovato. Now, it seems the singer/songwriter is expressing his love for sassy pop star Ke$ha on the site. He's also calling out all the haters for their criticism of Ke$ha's raucous pop.

"Stop telling your friends you detest the Ke$ha song and then dancing to it at home," he tweeted. "How about some accountability, people?" He later added: "How can you watch Jersey Shore for 9 hours and then act like you only listen to Beethoven's fifth? Okay. Point made. Night."

He also took to the site to personally reach out to the singer and joke with her about the lyrics to her hit song "Tik Tok." "Dear Ke$ha, you have won me over with your tricks and charms and I must tell you I really like your song," he wrote. "Though I must add I tried brushing with a bottle of Jack and I chipped a tooth on the glass. Where might I remit an invoice?"

Mayer's tweets were welcomed by Ke$ha, who responded with some lyrics from her latest tune, "Blah Blah Blah": "Dear john mayerrr. Don't be a little bi--- wit ur chit chat. Jus $how me whur ur di--'s at. X."

With Ke$ha's birthday on Monday (March 1), there's no word whether Mayer got her a present. But she made her b-day wishes clear on Twitter: "PS. IT'S MY MO F---ING BIRTH DAY. I want a baby whale with a lasso and an eyepatch. kk. and peace on earth n sh--. woot."
