The video then cut to a clip of Momsen, who played Cindy Lou Who in 2000's "How the Grinch Stole Christmas," receiving medical attention and showing her leg with red marks.

"A BAT flew onto me and clung to my leg ... in the moment I was performing and had no idea until the incredible crowd kept screaming and pointing ... he was cute, but yes he bit me ... so rabies shots for the next two weeks," Momsen wrote on Instagram.

According to the Centers for Disease Control and Prevention, bats are the "most commonly reported animals to have rabies" in the United States.

Momsen thanked the staff at the hospital for treating her and joked that they "dubbed me #batgirl after seeing it on the local news that morning." She used the hashtag "Batgirl" in the caption of several subsequent Instagram posts, one of which showed her walking off stage after being bitten. "He was very cute," she said of the bat.

In the comments, Momsen addressed a question from Natasha Bedingfield, who asked if it hurt. "The bite? No," she replied. "The shots? YES." But she maintained a sense of humor about the situation and on Saturday shared a photo of herself backstage posing next to a joking "no bats" sign. The Pretty Reckless said that the band's next show was "bat free thankfully."

The rock band is currently on tour in support of AC/DC, with upcoming shows scheduled for the Netherlands, Germany and Austria.
