Who knew John Mayer was such a huge Lady Gaga fan?

The outspoken 37-year-old singer randomly decided to show his love for the 28-year-old "Applause" singer on Twitter on Thursday, praising her for her latest solo album Artpop.

"I know this is going to sound like I'm trying to stir up media, but I have huge respect for Lady Gaga and I wanna tell you why," he tweeted. "She released a record that didn't get the love she was probably hoping for, which happens to REAL artists. And she's stood by it."

Artpop, Gaga's third studio album, was released in November 2013, and was considered a commercial disappointment compared to her 2011 smash album, Born This Way.

"There is no desperate attempt to be as successful as before by any means necessary, no Artpop 2.0 with cynically produced hits," Mayer added. "I respect artists who release music they believe in and with a slow steady pulse while doing it, live or die. So yah. fin. Carry on Gaga. I can dig it. Everyone else should, too."

Gaga returned the surprising love right back, tweeting in response, "Just got out of a great rehearsal! That was really cool @JohnMayer So thoughtful. The respect is mutual. ⚡️"
