WASHINGTON: Britney Spears' boyfriend Jason Trawick is like a natural dad to her two sons and treats them 'like his own', according to reports.

The pop princess was recently spotted with her kids, Sean and Jayden, and beau at the Tides Zihuatanejo resort in Mexico.

"Jason was great with the kids and you can tell Britney really trusts him," Us magazine quoted an eyewitness as saying.

"He would pick up Jayden if he wanted to be held, immediately calming the boy down," the eyewitness added.

A Trawick pal also said: "He is absolutely fantastic with the boys. When you see him with them, you wouldn't think for a moment that he wasn't their dad.

"He treats the kids like they are his own."
