Christina Aguilera has an arcade at home.

The 'Fighter' hitmaker - who has a three-year-old son Max with ex-husband Jordan Bratman - loves playing "old school" video games and claims no one can beat her top scores when they come to her house to play.

She said: "I'm a huge game nerd. I have a mini-arcade in my house, but it's like old school games like 'Donkey Kong' and 'Mario'.

"I hold the record for all of them. Everyone who has a little gamer in them comes over and tries to beat my score, and I get a little competitive. I'm number one on 'Galaga'."

The 30-year-old beauty - who is now dating set assistant Matt Rutler - has seen several fans with tattoo tributes to her, and she finds the inkings "sweet".

She added: "It's so sweet, it's so flattering. I don't know what to say when I see it, I'm always in awe."

Video game fan Christina recently admitted she expects she will be immortalised in another leisurely pursuit in the feature.

The blonde star famously forgot the words to the US national anthem when performing at the Super Bowl and said she thinks it will end up as a question in popular board game Trivial Pursuit.

She said: "That night I knew, I just made myself a Trivial Pursuit question - 'in 2011 what female singer, you know, flubbed the lyrics?' It's just insane. But I have a really good laugh about it and you get over things. You get back up again and you just prove to yourself and to everyone you're much stronger."
