At long last, there's been a Suri Cruise sighting.

As reported Tuesday on the CBS Evening News With Katie Couric, the daughter of actor Tom Cruise and actress Katie Holmes will appear with her parents on the cover Vanity Fair, which will hit newsstands on Wednesday.

Leading up to Tuesday's announcement, Suri Cruise had yet to be seen in public, either in person or photographically, since entering the world April 18.

To some, this had been a holdout of staggering proportions.

Us Weekly magazine is running a clock, ticking off the days since Suri's birth. German TV station RTL, taking matters into its own hands, produced a composite image of what Suri might look like. TMZ.com, perhaps digging for evidence of Suri's existence, obtained a copy of the official birth certificate, filed May 8 in Los Angeles. And gossip Web site Defamer.com called the delay "profoundly strange" and upgraded its suspicion from "mystery" to "riddle that would make the Sphinx incontinent."

The secrecy had been in stark contrast to the couple's radically public courtship. Cruise, 44, and Holmes, 27, spared no photo-op during their whirlwind romance. They are now engaged, though there has been no word on wedding plans.

The top Invisible Baby theory involves Cruise's Scientology beliefs. The religion's founder, L. Ron Hubbard, was very specific about how infants should be treated ?he taught that birth should occur in a silent environment.
