A source told Us Weekly: ''Kanye says he can't wait to see her carrying his child,'' a source revealed. ''He says she will look beautiful pregnant.''

Despite Kim, 31, having two failed marriages already, the insider added they she is keen to tie the knot with Kanye 35.

They said: ''They're seriously talking marriage. And yes, she would [accept his proposal].''
