Celebs praise Lady Gaga for her rousing Super Bowl 50 performance

Lady Gaga's Hollywood peers have come out in droves to congratulate the star on her spectacular performance at Super Bowl 50 on Sunday (7Feb16).

The 29-year-old Applause hitmaker kicked off the National Football League sporting event by singing her rendition of the national anthem The Star-Spangled Banner.

She belted out the tune in the middle of the playing field at Levi's Stadium in Santa Clara, California while standing onstage alongside a piano played by a lone pianist.

Gaga was visibly moved while singing, tearing up from time to time, but she still delivered a smooth, flawless show nonetheless, ending the gig with a rich long note while jet planes flew overhead in the sky above the venue.

Gaga was joined by hearing-impaired Oscar winner Marlee Matlin, who performed the song in American Sign Language, and the 50-year-old actress is elated to have taken part, writing on her Twitter account: "She is spectacular. I (love) you @ladygaga. Let's get together again and make magic - you singing me signing".

Other A-listers were also impressed, with Jessica Jones actress Krysten Ritter gushing: "Well @ladygaga wins the Super Bowl and every other single thing SLAY QUEEN!!"

Thespian Alyssa Milano felt shudders as Gaga performed, tweeting: "That was amazing @ladygaga. Chills. Everywhere."

Gaga's attire for the gig was very patriotic, as she donned a custom sparkly red Gucci suit made from lurex fabric that was designed by Alessandro Michele. Her makeup matched her clothes, as the star's bold red eyeshadow was coated in heavy glitter.

Comedienne Ellen DeGeneres admired the outfit, joking on Twitter: "Love you so much, @ladygaga. I'm so glad I loaned you my jumpsuit."

Gaga's singing peers were also dazzled by the act. Gaga is currently in the running for a Grammy in the Best Song Written For Visual Media category for her Oscar-nominated Diane Warren collaboration Til It Happens To You, from documentary The Hunting Ground.

And Diane couldn't be more proud of her colleague, writing: "So proud of U @LadyGaga!!!!!!!!!!!!!!!!!!! And 3 wks from today.....#OSCARS #TilItHappensToYou!!!!"

Gaga and Warren will learn if their song has won an Academy Award when the Oscars take place in Los Angeles on Sunday 28 February (16).
