She's a true friend!

Giulana Rancic flew back to Los Angeles yesterday after attending Joan Rivers funeral in New York over the weekend, and the E! host seemed like she was still mourning her former co-host as she made her way through the airport.

When asked about the late 81-year-old comedienne, the Fashion Police star gushed, "No one can replace Joan." We wonder if the TV correspondent will be tapped to try and fill her shoes? While the future of their fashion show is still up in the air, it wouldn't surprise us if the network called upon the blonde beauty to step in as host of the program.
