Could it have only been a dream?

Reports had surfaced last week that in place of William Shatner coming back to Star Trek with a stint on "Star Trek: Enterprise," coming onboard instead would be Marina Sirtis and Jonathan Frakes, who played Counselor Deanna Troi and Cmdr. William Riker respectively in "Star Trek: The Next Generation" and four feature films.

But appearing at a convention in Orlando, Fla., this weekend, Sirtis said nothing of the kind is taking place.

"I spoke with Marina Sirtis at FX today," said Norm Liddell, a member of the Orlando-based USS Haven fan club. "She insisted that the story about her and Frakes on ('Enterprise') is a rumor, and is completely false. She says she has nothing going on with ('Enterprise.')"

It had been originally reported that Marina Sirtis' official Web site had the news about the guest appearance on the site. However, a current check of the site shows no such story there.

"Star Trek: Enterprise" airs Fridays at 8 p.m. ET on UPN.
