The donut only came by once a day. It was some of the best donuts of my life. I credit it for my butt! :) (sic), wrote Serena on her Twitter page.

The star was raised in Compton, Los Angeles County, and has fond memories of the areas unique dietary traditions. Another healthier gourmet treat the star enjoyed growing up was sweetcorn, which was also available for sale on the street.
