Poor Hillary Clinton can't catch a break with celebrities endorsing her.

Opening up for Amy Schumer at Madison Square Garden in New York City on Tuesday night, 58-year old singer and pop icon Madonna took the stage to unleash some comedy of her own.

Unfortunately, the Material Girl's jokes came a bit too strong, pledging she would perform sexual favors on anyone who voted for Hillary Clinton.

"If you vote for Hillary Clinton, I will give you a blowjob," Madonna told the audience. "Ok? I'm really good. I'm not a d***he and I'm not a tool. I take my time, I have a lot of eye contact and I do swallow."

Her comments were well received by the crowd, and Madonna joked that she was insanely jealous she's not a comedian when introducing her 'good friend' Amy Schumer, who was booed earlier this week in Tampa for ripping Trump supporters at her show.

From the looks of social media, however, Madonna's comments seem to be backfiring.

MADONNA WILL GIVE ‘B**WJOBS’ FOR HILLARY



IF YOU HAD A GUN TO MY HEAD, I WOULD NEVER VOTE FOR THE DEVIL!
