Megan Fox stepped out in style on her way to watch Machine Gun Kelly perform in Los Angeles on Wednesday. The 36-year-old actress couldn't be missed in a neon green Jacquemus halter top and matching pants on the afternoon of her fiancé's Mainstream Sellout Tour held at the Kia Forum. Fox has history with this particular shade of green -- last August, she showed off a bodysuit in the same color on her way to the grocery store and in February, she painted her nails to match.A post shared by Megan Fox (@meganfox)MGK is also drawn to the neon look.
