The 43-year-old singer stepped out in a baggy, dark tank top that hid her figure, and black skinny jeans. Gwen added a dash of colour to her look with red lace-up boots and her matching trademark bright lipstick.
The mother-of-two was accompanying her sons, seven-year-old Kingston and five-year-old Zuma, and her adorable niece Stella to the Disney Junior Live On Tour! event in Hollywood.
Gwen's youngest looked just as effortlessly cool as his mother in matching beige boots with neon orange laces, and a sleeveless red shirt and jeans.
Stella, meanwhile, seemed to be getting into the Disney spirit and looked cute in a patterned dress and blue princess crown.
Gwen held tightly on to Zuma and Stella as they arrived at the event, while the older Kingston was happy to walk around independently.
Rumours first emerged that Gwen was pregnant with her third child in August, when the star was spotted in London showing a more rounded stomach under a navy blue trench coat.
The married couple of eleven years have yet to confirm the news, despite an insider telling In Touch Weekly that the singer was expecting.
"Gwen and Gavin couldn't be happier," said the source. "She's just trying to focus on resting right now. She wants to make sure that all is well with the baby."
