If there is a second season of Bravo's reality show "Southern Charm," Thomas Ravenel won't take part in it.

Ravenel, 51, is planning an independent campaign for Republican Lindsey Graham's Senate seat in the fall.

"If there is a Season 2 of #Southern Charm, I will not be a participant," Ravenel said Monday night on Twitter. "I do wish the show the best though."

The former state treasurer and his girlfriend Kathryn Dennis, 22, also a cast member of "Southern Charm," had a daughter together March 24 in West Palm Beach, Fla., where Ravenel splits his time.

Bravo has not announced a renewal for the show, which follows the socializing of well-heeled Charlestonians. The show's first season finale was April 21.

A representative of NBCUniversal, which acquired the Bravo network, said he had "nothing to comment on at the moment" about the show Tuesday.

The Twitter accounts of cast members Shep Rose, Craig Conover, Cameran Eubanks, Jenna King and Whitney Sudler-Smith also make no mention of the confirmation of a second season, nor what their involvement would be, if any.

Recently, Rose opened a downtown restaurant, Conover graduated from law school, Eubanks got married and King seems to have her home base in Los Angeles. A post from Sudler-Smith shows him yachting with Prince Albert of Monaco in Cannes.

Ravenel's first dalliance into South Carolina politics ended when he was caught in a federal cocaine bust. Dennis is part of the Dennis family of influential figures anchored in Berkeley County.

Ravenel said he will run for the U.S. Senate as a petition candidate if Graham were to win this month's GOP primary.
