Still celebrating their March 26 wedding, newlyweds Reese Witherspoon and Jim Toth have been spotted this weekend arriving in Belize for a relaxing vacation.

But they weren't alone! Ava, 11, and Deacon, 8, Witherspoon's daughter and son with ex-husband Ryan Phillippe, accompanied Mom and her new husband on the family getaway.

A witness told Us, "They definitely looked like a happy family. The kids seemed like they had no problem with him around."

Witherspoon, 35, and Toth, 40, are said to be staying with the kids in the tiny Central American country for six days. Upon arriving, the Oscar winner reportedly blended in by dressing inconspicuously in jeans and a T-shirt, topping her look with a brown hat.

"They didn't ask for any VIP treatment," said the observer who saw the newlyweds moments after their landing. "[They] walked off the plane like regular tourists, waited in the immigration line and waited to get their bags from the baggage carousel."
