The musician – born Colson Baker – paired his laid-back look with a colorful T-shirt peeking out from underneath his hoodie, as well as black sweatpants.

The self-proclaimed Blonde Don chose to stay comfortable during the outing and wore a pair of black sneakers.

His lady love completed her look with a blue denim baseball hat and a pair of black and white Nike sneakers.

The couple reportedly sealed the arrangement by drinking each other’s blood.

Last week MGK accidentally referred to Megan as ‘my wife’ during an episode of The Ellen DeGeneres Show.

The Rap Devil hitmaker was recollecting his embarrassment over their massage therapist diagnosing his allegedly gassy gut during an appointment at their new LA home.

‘My wife is right there! No, no, no,’ MGK recalled saying to his staffer.
