Lady Gaga nails national anthem at Super Bowl 50

Lady Gaga sang "The Star Spangled Banner" at Super Bowl 50.

(CNN)Lady Gaga's rendition of the national anthem, which kicked off Super Bowl 50, has fans of the singer going gaga for her sweeping vocals.

Gaga opened the show at Levi's stadium in Santa Clara, California, with a gospel-inflected performance of "The Star-Spangled Banner."
    Actress Marlee Matlin, who is deaf, signed the anthem.
    Wearing a glittering red suit and matching eye shadow, along with American-flag inspired shoes, Gaga belted out the anthem into a silvery microphone.
    The singer and star of "American Horror Story" is one of many big names to grace the stage at this year's Super Bowl. Coldplay will perform along with Beyonce at halftime. Bruno Mars is scheduled to make an appearance.
    The Grammy award-winning and Oscar-nominated singer and actress is famously dramatic -- her delivery and look didn't disappoint.
    Some folks on social media took the opportunity to rib Gaga about her resemblance to a certain flamboyant movie character: Effie Trinket of the "The Hunger Games."
