Secrets of the upcoming Oprah Winfrey Show from Vegas spill not only news from iconic divas, but of a Tom Cruise reunion in Colorado too.

Tina Turner, 68, told Oprah that ageless Sophia Loren asked when she was "going back to work."

Turner's first concert tour in eight years kicks off Oct. 1 in Kansas City.

The singer joined another legend, Cher, for a duel interview with Winfrey on stage at the Colosseum at Caesars Palace.

This Oprah will be broadcast on May 8, after Cher's latest Vegas show debuts.

The two singers performed Turner's song, Proud Mary, and discussed the hardships they endured after their divorces, piled up debts left from late husbands Sonny Bono and Ike Turner.

Cher performed a number from her Vegas show, Take Me Home, wearing a blue Bob Mackie dress with a matching blue headpiece flanked by a dozen dancers in 1970s outfits.

Winfrey will alos show footage of Cher and her long-time costume designer Mackie in his studio looking over some of the 17 costumes Cher will wear for the new Vegas review.

Oprah also hinted a bit at the long-awaited reunion with Tom Cruise in Telluride, Colo., since his career imploding couch-jumping moment in 2005.

Winfrey spoke of having to hold on to him during a snowmobile ride.

"There's something about being scooched up to his butt that makes you want to sing Take Me Home, Tom," Winfrey said. "Now I know what (his wife) Katie (Holmes) sees!"

The new Cruise episode airs this Friday.
