Regis Philbin, six weeks removed from triple heart-bypass surgery, plans to be back at work Thursday morning as cohost of Live With Regis and Kelly.

Philbin's first guest will be David Letterman, also a veteran of bypass surgery.

"Very appropriate," Philbin's cohost, Kelly Ripa, said as she announced her partner's return yesterday.

Philbin, 75, filled in as a guest host on CBS's Late Show after Letterman had his bypass operation in 2000. Rege also subbed for Letterman when the late-night guy got an eye infection in '03.

Fathers and sons

The celeb Web site TMZ.com is reporting that Sean Stewart, son of raspy rocker Rod, got himself involved in what Dad might call a spot of bother Saturday night that has attracted the notice of Los Angeles police investigators.

The younger Stewart, who stars in the A&E reality show Sons of Hollywood, apparently got into a hassle with partygoers at a shindig in a Hollywood home.

When he and two buddies were told they weren't welcome, the three threw rocks, bricks, a mailbox and a trash can at a Ford F-150 pickup truck, according to TMZ.

Witnesses said the trio then proceeded to rough up the occupants of the pickup, a husband and wife, TMZ reported.

Police confirmed that detectives were looking into the incident, according to the Web site.

TMZ could not immediately reach Stewart's rep for comment.

Actor

Sam Elliott

and the late actor

Steve McQueen

have been inducted into the Hall of Great Western Performers at the National Cowboy & Western Heritage Museum in Oklahoma City.

The two were honored at the 46th annual Western Heritage Awards on Saturday, with Elliott, 62, acting as master of ceremonies before a sellout crowd of more than 1,200. McQueen died in 1980.

Stuntman Dean Smith lassoed the board of directors' Lifetime Achievement Award. Smith has risked life and limb as a stunt double for an all-star roster of celluloid range riders, including Roy Rogers, Dale Robertson, Ben Johnson, Robert Redford, Robert Duvall and Steve Martin.

"What a great night you've made for this old cowboy. I'm glad to be included in this museum with all my heroes," said Smith in aw-shucks western fashion.

Truce (2005), starring Buck Taylor and Michaela Lange, was honored as the outstanding theatrical western movie, and Broken Trail (2006), starring Robert Duvall and Thomas Haden Church, won the award for outstanding television western feature.
