Miranda Cosgrove: Smiley Face Sweet

Miranda Cosgrove keeps it super comfy in a smiley face sweatshirt as she holds onto her iPhone in Los Angeles on Sunday evening (April 12).

The 15-year-old iCarly cutie was seen heading to her math tutor on Saturday afternoon, catching up on her quadratic formulas.

In the next episode of iCarly, “iGo Green,” Carly (Cosgrove) inadvertently builds an illegal nuclear-powered generator while trying to complete a school assignment for an environmental project.

“iGo Green” airs next Wednesday, April 22 @ 8PM ET/PT on Nickelodeon.
