Avril Lavigne had to go and make things so complicated by swearing during a baseball game at the weekend - and now she's had to apologise.

The 26-year-old Canadian singer burst into an expletive-filled rant during the Tampa Bay Rays' game in Tampa, Florida on Saturday.

Unfortunately, her F-word rant was heard by over 24,000 people.

Lavigne had experienced technical issues during her performance at the game which gave way to the crowd booing her.

She then hit back saying that 'sound problems f***ing happen on a baseball field.'

Later that night, the Complicated singer apologised for losing her temper.

'We just had so much fun tonight and we want to take the tirade out and say thank you to the Tampa Bay Rays!' she told the audience.

'I'm truly sorry if anyone was offended by my language', she said contritely
