A CBS daytime soap will pay a winking tribute to one of the network's biggest prime-time soaps later this spring.

Larry Hagman is scheduled to make a cameo appearance on "The Bold and the Beautiful" in May, CBS says. The brief role will reunite him with his old "Dallas" co-star, Linda Gray.

Gray is now a regular on the daytime drama, having joined the cast this year. She'll meet up with Hagman's nameless character on a flight to (where else?) Dallas, when he asks if the seat next to her is taken.

Hagman and Gray were a TV couple for a decade on "Dallas," the long-running CBS drama that was a Top 10 show for seven straight seasons from 1979-86. Hagman earned two Emmy nominations for playing despicable oil baron J.R. Ewing. Gray earned one herself for playing J.R.'s boozy, long-suffering wife, Sue Ellen. Both reprised their roles in "Dallas" TV movies in 1996 and 1998.

Hagman has worked rather sparingly in recent years, appearing in "Primary Colors" and the short-lived 1997 series "Orleans." Gray's post-"Dallas" credits include the TV movie "When the Cradle Falls" and a starring role in FOX's "Melrose Place" spinoff "Models Inc."
