"We're missing my sister cuz she in the back sewing costumes! #FamilyMatters #PepsiHalftime #SB51," Gaga captioned a shot of herself sprawled across the field in a fierce black ensemble, as her parents smiled next to her.
The "Million Reasons" singer also shared a hilarious behind-the-scenes video from her dressing room, as she danced around in a pink football uniform and some underwear.
"Gettin' too funky in the dressing room. While my best friends side eye me from the couch for bein a ham ? so happy my friends and family are. Let's go men it's gametime!?????⚡️," she captioned the clip on Instagram, before sharing a video of an impressive pre-game jump.
Gaga, who also hopped on Snapchat before getting all glammed up to document her morning routine with fans, is giving Sunday's game all she's got -- and despite rumors of special guest stars during the Pepsi Zero Sugar Super Bowl Half Time Show, she said she's doing it on her own.
"I want to say thank you to my fans for cheering me on all these years. There will not be any guest performers tonight, I'm doing these 13 minutes solo!" she revealed on Instagram. "I dedicate every second to the love, diversity, compassion, and wild spirit of our fan base. To that kid who felt unwanted, or the grown up who remembers how hard it was to find acceptance. This is for you."
"It is also for those whose hearts and minds have opened to our message. Thank you for believing in us so we could be here today little monsters this is YOUR stage. And I'm gonna leave my heart on it so you never forget it. Let's do this," she wrote. "Xoxo Love, Gaga."
