NBC will air a new episode of All Star Celebrity Apprentice on Sunday and it will offer a surprise twist: Bret Michaels,this season's loser from week 1, will return as an adviser.

In the preview clip, Michaels partially explains the reason for his return in the episode where he sits on the other side of the Boardroom with Donald Trump.

"I feel like I was let go unjustly," Michaels says in the clip.

Michaels, who won Celebrity Apprentice Season 3, returned this season to compete for more money for his charity and Trump seemed to not agree with the idea so the rock star was fired in week 1.

Sunday's episode will also showcase Lisa Rinna and Penn GIllette's frustrations of working with their Team Plan B member Gary Busey. Busey, who narrowly escaped being fired last week, is busy doing everything else but putting efforts into this week's task.

This week the two competing teams must create an interactive travel expo for South Africa Tourism. In the preview clip, Rinna vents her frustration.

"Gary is off being Gary, I don't know what he's doing," Rinna says. "Working with Gary is probably like working with a three-year-old. No focus, no direction, no nothing," she adds. "He's probably more focused on eating his chicken."

All-Star Celebrity Apprentice airs Sundays at 9p.m. EST/8 Central on NBC.
