They were after Ryan!

TMZ has learned that just moments ago, "E! News" host Giuliana DePandi and a slew of other E! Entertainment Television employees were evacuated from their Los Angeles office building after a "bomb threat" was phoned into security.

Sources tell TMZ that two threatening phone calls were made from two different overseas locations.

We're told that Ryan Seacrest was not in the building at the time of the evacuation. Police sources tell TMZ that a security guard on scene reported the threats, and LAPD is currently at the location.

The EMI-Capitol Music Company and the G4 Network are also occupants of the building. The structure was used as the D&D Ad Agency in "Melrose Place!"

A source tells us that occupants of the building are being told that they will be kept out for at least an hour.
