They're growing up SO fast! Megan Fox and Brian Austin Green's three kids, Noah, 12, Bodhi, 11, and Journey, 9, were just spotted in a super rare pic with their half-brother Zane as the 3-year-old celebrated his first day of pre-K! Aw! Momma Sharna Burgess shared videos of the older siblings hyping up the little boy as he held up a sign listing his favorite things. The three other kids then joined him for a sweet snapshot.
