Gwen Stefani yello jeans boots no doubt birthday party superhero Elizabeth Glaser Pediatric AIDS Foundation's 24th Annual When you're this fashionable, one outfit just won't suffice!

Gwen Stefani had a busy day yesterday! The No Doubt front woman donned colorful yellow jeans and a white T-shirt to take sons Kingston and Zuma to a birthday party in the morning, but by the afternoon she was in a totally different ensemble ready to attend a charity function with her adorable family!

The blonde beauty wore motorcycle boots, loose-fitting khakis, and a black blazer to the Elizabeth Glaser Pediatric AIDS Foundation's 24th Annual "A Time For Heroes" event, and even dressed down she still looks like a true rockstar everywhere she goes!
