Megan Fox and Brian Austin Green Dote on Kassius

Helping her boyfriend as he doted on his young son, Megan Fox and Brian Austin Green ventured out shopping at Office Depot in Los Angeles on Saturday (January 31).

The "Transformers" hottie and her "Beverly Hills 90210" beau escorted his 6-year-old son Kassius around as the group busily stocked up on school supplies.

As previously reported by Gossip Girls, Kassius Lijah was born to Brian and his former squeeze Vanessa Marcil, who is an actress known for her role on "Las Vegas".

On a side note, Miss Fox also recently shocked everyone by announcing that she isn't going to get involved in taking over Angelina Jolie's Lara Croft role in the new Tomb Raider movie, as her rep dismissed reports, saying, “Megan is not involved in this movie.”
