After country singer Blake Shelton took his pop star girlfriend Gwen Stefani to his native in Oklahoma last week, the two paid visit to the latter's hometown in Anaheim, California.

The two were spotted hanging out together in the Southern California city on Tuesday, reports etonline.com.

An onlooker said that the couple was spotted with Stefani's parents and her three children - Kingston, 9, Zuma, 7, and Apollo, 1 -- alongside her ex-husband, Gavin Rossdale.

The two were spotted holding hands and kissing each other.

"Gwen's kids seemed approving of Blake," the onlooker said.

At one point, the couple stopped by Cortina's Italian Market & Pizzeria.

One fan took a photograph with the duo and posted it on his Instagram page.

A caption for the image read: "Just helped out Gwen Stefani and Mr. Blake Shelton!#blakeshelton#gwenstefani #cortinasitalianmarket."
