Mila Kunis is very excited about her baby's arrival but she's also feeling 'pretty big' as the due date is getting closer, particularly after her boobs 'tripled in size'.

Sources told People magazine that Ashton Kutcher can't wait to do tons of stuff with the baby and the 30-year-old actress was feeling good as the things are going smoothly, however, she does feel pretty big lately but can't do much because it's harder for her to move around, the Mirror reported.

The 'Two and a Half Men' actor runs all the errands alone so that Kunis could stay home, sources added. Kutcher has been looking after Kunis throughout her whole pregnancy and has become even more protective as she has reached the final trimester.
