On the cover of the mag, "The Voice" coach gives her 7-month-old a smooch on the cheek. Summer, with eyes a surreal shade of blue, giggles with her lil' baby tongue lolling out.
Before the cover reveal, the only pictures we had seen of Summer were baby bumps and this adorable diaper pic on her Instagram:
Xtina gave birth to her daughter on August 16. Summer is little sister to 6-year-old Max. You'll see the adorable siblings together when the mag comes out on Friday.
