Rob on His 'DWTS' / 'KUWTK' Wedding Rivalry

Last night ushered in week four of the Dancing with the Stars competition, and at this decisive point in the game, the contestants need all the support they can get. As evidenced in Monday night's crowd of proudly shining faces, not one of the nine couples seemed to lack in the family department.

While Cher has consistently lent support for her son via Twitter during the competition, the music/film legend made her first appearance to the set last night, spotted tearing up during Chaz's empowering dance set to the Rocky films' theme song.

"It was a great night for me," Chaz told Entertainment Tonight's Mark Steines after learning he'd just scored his highest numbers of the season.

"Having my whole family there pumped me up," he beamed. "Doing this in and of itself is so nerve wracking."

Rob Kardashian was another who no doubt excelled this week with the support of his family. With mother Kris Jenner and stepfather Bruce Jenner looking on, Rob took home three eights to land him and partner Cheryl Burke one of the highest scores of the night.

Although he admits he's "got to support the Kardashian name" it seems the sibling rivalry is still going strong. As Mark Steines playfully reminded Rob that Monday's DWTS would be going head to head in the ratings with his sister Kim's wedding special, he grinned mischievously and replied he "would rather have people vote for us than watch that show."
