Oprah Winfrey is careful not to smother her young nieces whenever they pay her a visit because she hated hugs from her big-breasted grandmother when she was small.

The Tv titan and actress insists her boobs are getting bigger as she gets older - and she's convinced she's carrying around her grandma's "breasteses".

Promoting her new movie The Butler on U.S. chat show Watch What Happens Live, she says, "They really are big. The other day I went like, 'God, are y'all getting bigger?'

"These are my grandmother's; she is with me... When I was a little kid I'd see my grandmother coming and I'd go, 'Oh no, oh no... Hug me!' So now, when I see my young nieces, I'm aware of that. I'm like, 'Come here honey, come to the side'."
