Myleene Klass and AvaMyleene Klass and AvaMyleene Klass has had a grilling.

She was was held at Heathrow airport by immigration officials.

And you won't believe the hoo-ha...

They refused to believe her baby daughter was hers.

Myleene was merrily going through the motions at the airport on her return from a working trip to Australia with 11-month-old Ava, but without fiance Graham Quinn.

You'd think that would be pretty straight forward, right?

Well think again...

She told The Sun: "They looked at Ava’s passport and said, 'Are you sure you’re her mother? Her name is Quinn.'

"I was just made to feel like I was baby smuggling or kidnapping my own daughter.

"They held me for ages before they let me go. What did they want, a DNA test?"

Crikey, well at least it's reassuring that they run a tight ship.
