Pregnant Celebrities: Who's Expecting?
Jack Osbourne and wife Lisa announce they're expecting their second child later this year...
Beyonce is seen discovering she is pregnant in a newly unveiled trailer for the US star's upcoming HBO documentary film.
The Love on Top gave birth to her and Jay-Z's first baby, Blue Ivy Carter, last January.
'I just had a feeling that something was going on,' Beyonce is seen saying in home-shot footage taken just after she discovered she was expecting, while a sonogram picture of the baby is also shown. 'This is crazy!'
Beyonce also opens up on her feelings about being a celebrity as well as the pressure she feels in her career to stay at the top of her game.
'How do I say current? How do I stay soulful?' Beyonce questions in the clip. 'I felt like I had been so commercially successful [but] it wasn't enough.
'It's something really stressful about having to keep up with that, you can't express yourself. You can't grow,' she added. 'It is the battle of my life, so I set a goal. And my goal was independence.'
