May 30 (UPI) -- Britney Spears posted a new photo Tuesday of her growing sons.
The 36-year-old singer shared pictures with 12-year-old Preston and 11-year-old Jayden, her children with ex-husband Kevin Federline, from an outing Sunday.
The slideshow shows Spears and her sons enjoying a meal at their "favorite spot." The post had received over 519,000 likes as of Wednesday morning.
"Love when we go to our favorite spot on Sundays," Spears wrote. "The boys are bigger than me now!!!!"
The "Slumber Party" singer called her sons her "world" in an Instagram post earlier this month.
"Nothing makes me happier as a mom than watching these boys grow and smile and laugh!! They are my world and I love days like this when we get to just run around and play together," she wrote.
People reported last week Federline is requesting an increase in child support from Spears. Federline said he earns $3,000 per month and presently receives $20,000 per month from Spears in child support.
"We think the reasonable needs for the children while they would be in Kevin's custody is probably three times what he's currently receiving," Federline's attorney, Mark Vincent Kaplan, told the magazine.
