He "gave [a ring] to her for her birthday," claims a source. "It's not an engagement ring and they're not engaged. It was a surprise gift from him."
They may not be getting hitched, but both of them have met the each other's families. And that includes her son, Max! Matt and Max met on an outing to the Peterson Automotive Museum in El Lay.
"Christina took Max on the fun outing so he could bond with Matt," added the source. "Max was initially a bit shy, but later warmed up to Matt. It seems very important to Christina that Max got along with Matt."
Very sweet. Maybe there is an engagement in the near future!
