Christina Aguilera did a spot-on impression of Britney Spears on Monday's episode of "The Tonight Show."

In the talk show, Aguilera agreed to play "Wheel of Musical Impressions" with host Jimmy Fallon, Hollywood Life reported. When her turn came, the generator picked Spears as the singer Aguilera had to imitate while singing "This Little Piggy."

The 34-year-old pop diva's impression of her fellow singer was so on point that the audience, and even Fallon, cheered her loudly and gave her a standing ovation.

"Oh, my God! That is something I've always wanted! That is amazing. I loved that so much!" Fallon exclaimed, as quoted by E! News. "That was fantastic. Hard to top that, but I'll try."

Back in 2003, Spears said in an interview that she thinks her voice is OK and that she envied Aguilera's vocal talents, E! News noted.

Aside from Spears, the "Lady Marmalade" hitmaker also impersonated her "Burlesque" co-star Cher and Colombian singer Shakira, E! News wrote. For the Cher number, Aguilera sang the Folgers Coffee jingle, then went on to imitate her fellow "The Voice" judge Shakira in the final round singing the "Golden Girls" theme song.

During her appearance on "The Tonight Show," Aguilera discussed what it's like to raise her two children: Max, her 7-year-old son with Jordan Bratman, and 3-month-old Summer Rain, her daughter with longtime boyfriend Matt Rutler. According to the singer, raising a boy and a girl has its differences, E! News reports.

"She's a gem," Aguilera said, referring to her daughter. "There is a big sensitivity level. It takes a little while longer to calm her down. She's a girl. She's more emotional. It takes her forever to quiet back down. She's the best." E! News quoted.

As for her son, the singer reveals that Max is "so into being a daredevil. "He gives me a heart attack. He comes home and he's like, 'Mom, I want to take parkour lessons.' I'm like, 'What is parkour?'...I had to figure it out, but it's kind of like-do you guys know American Ninja Warrior? I'm kind of obsessed with it...I love it, but I don't love it for him," she said, as reported by E! News.

Aguilera added, "I'm going to put him in gymnastics or something so he can focus and be good at maintaining his monkey abilities. He's crazy. He's like a little monkey."

In addition to "The Voice," Aguilera is also set to appear as a guest star on "Nashville." She will portray Jade St. John, a pop star who wants to record a country album, Daily Mail wrote.
