The Hollywood baby rumour mill went into overdrive yesterday when Katie Holmes was spotted out shopping with a lot more rounded-ness in that usually flat belly of hers. With family-loving Tom said to be desperate to add to their brood of three, it looks like Katie, who has no more movies in the pipeline after wrapping on Jack and Jill, in which she’ll star alongside Adam Sandler, is planning a career break to focus on baby number two. \"Katie loves being a mum,\" spilled a source. \"Having Suri, as well as hanging out with Connor and Isabella is what her life is all about.\" And with Tom finishing up work on the fourth Mission Impossible movie, insiders say the family are getting ready for some serious nesting time. \"Connor and Isabella are great kids, a great brother and a great sister to Suri, and she’s a great sister to them,\" Katie recently told The Times. \"It’s not, ‘This is stepmotherhood and this is motherhood’. I’m not worried about [having another baby\". Suri’s got really good friends and great cousins, so I feel happy about it.” Adding, “We have a really busy household, and it’s really fun and fulfilling. There’s always something going on.” Another baby TomKat? We are so excited already!
