Tulisa Contostavlos shaken after earthquake scare

Singer Tulisa Contostavlos was left shaken after she was caught up in a terrifying earthquake in Bulgaria this week.

The N-Dubz star jetted to the European country to see her actor boyfriend Jack O'Connell on Monday, but their time together was interrupted when the tremor struck early Tuesday morning.

The frightened singer posted on her Twitter.com page, "WWWtttff (what the f**k) how can I just get caught in an earthquake... Thought the whole building was coming down... Thought it was The Exorcist looool (laugh out loud). I can't b**ody sleep after that... I've been in a few earthquakes but that was the strongest... Twas (sic) a lot... Building was swinging."

Skins actor O'Connell added on his Twitter page, "Just about pooed myself - heroic".

It wasn't the only drama on the trip for Contostavlos - her journey to Europe was delayed after her personal assistant reportedly became embroiled in a scuffle at an airport in Scotland before she jetted to Bulgaria.

The Daily Mirror reports Gareth Varey was headbutted in an argument with an unnamed man and police stepped in to settle the dispute. A spokesperson for Strathclyde police says, "We were called to an incident within Glasgow airport involving two people. They were both spoken to and no complaint was made."

A spokesman for Tulisa adds, "There was an argument at the airport but no further action is being taken."
