Paris Hilton - for bump pics see belowParis Hilton - for bump pics see belowIs there something Paris Hilton isn't telling us?

There are rumours circulating in the States that the hotel heiress might well be pregnant.

In recent pictures, there does seem to be a slight bump on her usually flat tummy - but of course that could just be due to too many beans and pulses making her full of wind.

But Paris herself has never made it a secret that she's keen to be a mother...

Plus there was her recent engagement to her young man, Paris Latsis, not a quickie in Hollywood standards but they certainly haven't been walking out for many a moon.

Whilst out and about visiting a juice bar in Beverly Hills - note the healthy juice option - Paris showed that she isn't just about parties and frocks and hair-flicking.

Instead the reality TV star dug deep into her pocket (well, her purse as pockets are apparently so last season darling) and handed over a twenty dollar note to a homeless person.

Needless to say, as he reached out for the money - which she offered through the open window of her car - the guy looked extremely impressed.

Perhaps he was marvelling at her multi-tasking skills - being charitable and nattering on her mobile at the same time.
