Pucker up!
Gwen Stefani took a short break from her tour on Tuesday to post adorable pics of a family day with her kids, including one in which she shares a sweet smooch with her oldest son, Kingston. 
"Kiss," Stefani captioned the pic on Snapchat.

While 10-year-old Kingston stayed close to his mom throughout the day, he did have to share her attention with his brothers, Zuma, 8, and Apollo, 2, as well as her friends and tour staff, who joined them on the trip.

Last Sunday, though, it was all about Zuma, as Stefani, 46 brought out the neighborhood -- and beau Blake Shelton -- to help celebrate her middle son's birthday.

But back to Stefani's little smooch -- she isn't the only celeb mom to make headlines for kissing her child on the mouth.
Just last month, Victoria Beckham received backlash (and support) for posting a photo of herself and daughter Harper sharing a kiss on Instagram.
