It was a fleeting encounter, lasting only two minutes. But for the Leader of the Free World, meeting the Queen of Pop was apparently an “intimidating” affair.

“She was wearing 16-inch heels. She was eight feet tall. It was a little intimidating,” President Obama said of pop superstar Lady Gaga in an address Saturday at the annual Human Rights Campaign gala in Washington, D.C.

The two met for the first time in person last week at a fundraiser for Obama’s re-election campaign held at the California home of Facebook’s Sheryl Sandberg and her husband David Goldberg.

Gaga reportedly wore a black dress, scalloped high plunge back and high heels. Her blond hair was upswept, with black flowers and black veil sweeping down back of hair.

“I held some productive bilateral talks with your leader,” Obama jokingly told the gaga-for-Gaga crowd of gay and lesbian advocates of the meeting, drawing hearty laughter and applause.

While it’s unclear what the two discussed, Gaga had tweeted before the fundraiser that she wanted to  raise the issue of youth bullying with Obama following the suicide of Jamey Rodemeyer, a 14-year-old Gaga fan who had been victimized for being gay.

“I am meeting with our President. I will not stop fighting. This must end. Our generation has the power to end it. Trend it #MakeALawForJamey,” the singer posted to twitter.
