WESTWOOD, California -- On Monday night, some of Hollywood's biggest stars descended on the Mann Village Theatre for a huge premiere, celebrating the summer's biggest, loudest, most high-profile movie. But on the [movie id="369059"]"Transformers: Revenge of the Fallen"[/movie] red carpet, moments before the film was unveiled, the day's news involving [article id="1614453"]Chris Brown and Rihanna[/article] was on everyone's lips.

"Violence is never the answer -- even if provoked," reasoned Aubrey O'Day, the former [artist id="2400155"]Danity Kane[/artist] member and "Making the Band" star, who had just heard the news that [article id="1614470"]Brown accepted a plea deal[/article]. "But with bigger issues like war, we just need to let go and forgive. Let people move on."

(Look back at a [article id="1614468"]timeline of the five months that followed Chris Brown and Rihanna's altercation[/article] on February 8.)

"I just wish they were here," "Transformers" co-star [movieperson id="254877"]Tyrese[/movieperson] said of Chris and Rihanna, explaining that the escapism of a film like "Revenge of the Fallen" is helpful during difficult times. "[It would help them] to embrace this energy at this premiere."

Sure enough, a huge crowd had poured out for "Fallen" -- but as the stars tried to promote their Friday release, it was hard to ignore the news that had broken just a few hours earlier.

"I wish [Chris Brown] luck," confessed "Gossip Girl" actress [movieperson id="245371"]Taylor Momsen[/movieperson], who was doubtful that the plea deal was the final chapter in the Chris Brown-Rihanna drama. "People like to obsess over personal lives -- so I'm sure it's not the end."

"I support both artists," said [artist id="1801883"]Ciara[/artist], who has toured and recorded with both Brown and Rihanna. "It's a very personal process."

[artist id="1231961"]All-American Rejects[/artist] member Nick Wheeler, however, was a bit less diplomatic. "If it was just a regular dude, would [the sentence] have been the same?" he asked, posing a question on the minds of many who believe Brown's celebrity helped him in the courtroom. "No one should turn a blind eye to [abuse]. He should get what he gets.

"We did a show with Rihanna a couple years ago," Wheeler added. "And she was nice."

"I wish them well," explained Anthony Anderson, a star of the original "Transformers" film, who said that he'll continue to buy Chris Brown albums whenever the troubled singer decides to move forward. "I'm not going to let a personal instance taint my opinion of someone musically."

"He's incredibly talented," Aubrey O'Day agreed. "Regardless of his personal decisions, I will always support his music."
