I was watching this movie today and realized my copy has one scene missing. Bruce increases Grace's boobs size which she realizes later (the morning after)
Can anyone link me the complete scene in which Bruce with the flick of a wrist does the job ?
There is no such scene. The only one in the movie is the scene of her saying they feel bigger at breakfast.
There were however 3 more boob-related scenes in the movie, which can be found in the script (http://www.imsdb.com/scripts/Bruce-Almighty.html). One was during the "Little Less Conversation" montage, where Grace is struggling to get her bra on because of their size. One is just before Bruce answers the prayers, where Grace has huge boobs, and says she needs to go to a doctor. The 3rd is Grace being back to normal after she prayed for it.
None of these additional scenes made it into the DVD extras, though the first one was on a foreign trailer. All that can be found of it is this screenshot: http://i234.photobucket.com/albums/ee181/pokemainiac/11_zpse953527a.jp g
