Rumors are abound from an inside source that Comcast Corp., the nation's largest cable operator, is in talks with The Walt Disney Co. to buy the remaining 40% of E! Networks it doesn't already own.

The Hollywood Reporter reports E! Networks, which is comprised of the E! celebrity channel and the Style fashion channel, is valued at around $3 billion.

Disney had no comment, company spokesman David Caouette said Monday night. It's unclear how much Philadelphia-based Comcast would pay to acquire the rest of the network from Disney, which is based in Burbank, California, or how long it might take to strike any agreement.
