Sorry guys, Megan Fox is officially a one-man woman. The former Transformers hottie married her longtime boyfriend, ex-Beverly Hills, 90210 star Brian Austin Green, during a clandestine ceremony in Hawaii late last week, tattling tipsters tell TMZ.com.

The couple said “I Do” in front of a small group of friends at the Four Seasons Resort on Hawaii’s Big Island last Thursday.

Brian and Megan met on the set of the now-defunct TGIF comedy Hope And Faith in 2004. They first announced their engagement in 2006. The couple split in early 2009, but ultimately reconciled and got re-engaged last month. This is the first marriage for both, although Brian has an eight-year-old son from a previous relationship with actress Vanessa Marcil.

Kassius joined his dad and new step-mom for the special occasion. Brian celebrates his 37th birthday on July 15.
