PHOTOS: 2013 Grammy Red Carpet

(Yahoo!) - Chris Brown and Rihanna didn't walk the red carpet together at the Grammy Awards Sunday, but they did sit next to each other at the year's biggest music event.

In 2009, the couple canceled their scheduled appearances at the show on the day of the event after Brown assaulted Rihanna. This is their first time reuniting for the festivities.

Their unified Grammy showing sparked sarcasm from Twitter users who were convinced that Brown would relapse.

"Chris Brown and Rihanna are sitting together at the Grammys because everyone deserves a 673rd chance," Robfee wrote.

Brice_j_Johnson added, "Rihanna flinches every time Chris brown starts clapping LMAO."

Dean Eddy, a therapist for Southern California Counseling Center, expressed concerns about Brown and Rihanna getting back together.

Eddy, who has been counseling couples for 20 years, said he did not think "52 weeks [of therapy] is enough time for [Brown] to really most past that."

Eddy said it important that Brown takes responsibility for his actions. "If he was really looking at the issues and owning for himself where the decision came from for him to actually strike her, there's a good chance he wouldn't do it again," he said.

Brown and Rihanna have spent a lot of time together this week.

Brown was consoled by Rihanna Saturday after he was involved in a car crash while attempting to evade paparazzi.

In a pre-show interview with Ryan Seacrest, Brown downplayed the incident. "I'm fine," Brown said about the crash. He said that he was not concerned about the car. "I'll get another one. Insurance is good."

He also did not make a big deal about the paparazzi. "A couple crazy paparazzi can tend to get out of hand. It's still good," he said. "Tonight, I'm just looking forward to the performances."

After Brown’s accident, he attended the 2013 Roc Nation Pre-Grammys Brunch at the House Of Blues in West Hollywood where he was greeted by the “Diamonds” singer. According to, they embraced and held hands.

The rekindling of their romance has sparked a backlash from fans. Just Jared user Pumkin slammed Rihanna for getting back together with Brown. “Last Pre-Grammy party they attended, we all know what happened,” Pumpkin wrote. “I never understood why women go back to abusers. The pics disgust me, I can’t imagine what it would actually feel like. Yuck.”

Another Just Jared user who posted a comment under the name ugh, complained about fans who believed Brown should be forgiven. “I sincerely hope that when your kids grow up you don’t have an abusive relationship because the way you disregard it scares me,” ugh wrote. “You wouldn’t forgive sexual abuse but you’d forgive domestic violence.. that’s a bunch of bullsh-t!!!!!!!”

Rihanna’s most shocking arrival with Brown this week occurred Wednesday when she escorted him to court. Rihanna blew Brown a kiss before entering court and sat behind him. Brown is accused of faking the community service requirement of his 2009 conviction for assaulting Rihanna.

In a recent cover story in Rolling Stone magazine, Rihanna responded to critics who did not support her decision to get back together with Brown.

"Even if it's a mistake, it's my mistake," she told Rolling Stone. "After being tormented for so many years, being angry and dark, I'd rather just live my truth and take the backlash. I can handle it."

Rihanna added that Brown knows that she would not stay with him if he ever hit again. "He doesn't have the luxury of f--king up again," she said. "That's just not an option. I can't say that nothing else will ever go wrong. But I'm pretty solid in the knowing that he's disgusted by that. And I wouldn't have gone this far if I ever thought that was a possibility."

Rihanna thinks the public should stop judging Brown. "He made a mistake, and he's paid his dues," she said. "He's paid so much. And I know that's not a place he would ever want to go back to. And sometimes people need support and encouragement, instead of ridicule and criticism and bashing."
