(CNN) -- Pop star Lady Gaga attended a political fundraiser for President Barack Obama in Silicon Valley Sunday evening.
The $35,800-a-person event for about 70 people was hosted under a tent in the yard of Cheryl Sandberg, the chief operating officer of Facebook.
Gaga tweeted to her millions of followers last week that she planned to meet with the president to discuss "how to stop bullying" after a teen took his life. It wasn't clear if they they talked at the fundraiser.
"Jamey Rodemeyer, 14 yrs old, took his life because of bullying," her Twitter post said. "Bullying must become be illegal. It is a hate crime."
Gaga dedicated a song to Jamey at a concert in Las Vegas Saturday night, while a tribute to the teen played on the video screens above the stage.
His mother, Tracey Rodemeyer, told CNN's Anderson Cooper last week that "it just seems like it was either end of the spectrum -- he was either loved so sincerely, or he was bullied. There wasn't much in between."
His father added that the taunting began in middle school and became progressively worse.
"We went to the school and got some help," Tim Rodemeyer said. "Eighth grade seemed to be a little bit better for him, but it was still continuing in eighth grade."
Jamey Rodemeyer took his life on September 18. His final Twitter post said: "bye mother monster, thank you for all you have done, paws up forever" and was included in her video tribute to him.
Gaga calls herself "mother monster" and her fans "little monsters."
