In photos obtained by Daily Mail, Fox came in red hot for the special day in a vibrant red Alex Perry suit with a matching triangular shaped bra and red platform sandal heels. The Transformers actress finished the look with red lips in the same shade and chunky gold hoops. Her long dark locks were waved and parted down the middle.
Machine Gun Kelly (whose real name is Colson Baker) wore gray slacks and a blue and red turtleneck, completing the look with black boots with red laces that matched her suit flawlessly.
The two are apparently closer than ever. Just last week, a source told Entertainment Tonight that Kelly "would marry Megan in a heartbeat." The source added that Fox is definitely "in love" with the singer but is more hesitant to jump right in to taking the next step because of her children she shares with ex husband Brian Green.
"She really takes her kids into consideration and knows that taking that next step would be a big adjustment, but it's not off the table," the source said.
