Spears stopped her Singapore show on June 30 to wish her bodyguard, Jacob, a happy birthday.
“I have a really special friend tonight. He’s been with me -- I’m gonna cry -- for, like, five years. He’s one of my favorite people, his name is Jacob," she told the audience. "Everyone, let’s sing 'Happy Birthday!'"
During an appearance on an Israeli TV show last week, Spears addressed lip sync rumors, declaring that she's "busting [her] a**" by singing live during shows.
"A lot of people think that I don’t sing live. I usually, because I’m dancing so much, I do have a little bit of playback, but there’s a mixture of my voice and the playback," she explained. "It really pisses me off because I am busting my ass out there and singing at the same time and nobody ever really gives me credit for it, you know?"
The singer recently wrapped her tour dates in Asia. See more in the video below.
