Orlando Bloom was so determined not to miss the birth of his son, he urinated in a bottle in the delivery room rather than make a trip to the bathroom.

The British actor and his model partner Miranda Kerr became first-time parents in January when they welcomed a baby boy named Flynn.

Kerr has now revealed she ordered her husband to stay by her side throughout the entire labor, and he didn't even leave her for a bathroom break.

She tells Harper's Bazaar Australia, "He was there every moment by my side. I never even let him go to the bathroom... he had to pee in a bottle."
