The event will honor veteran singer/songwriter
Hudson has remained secluded since the murders, which resulted in charges on December 2 against her brother-in-law, William Balfour, who faces three counts of first-degree murder and one count of home invasion.
It was reported last week that Hudson, 27, was to begin filming on a video for her single "If It Isn't Love," but a spokesperson said those plans were never finalized and the shoot did not take place. Hudson has not performed and has rarely been seen in public since the murders, though her name has popped up frequently in rumors about possible performers at President-elect Barack Obama's inauguration on January 20.
The annual MusiCares event will honor Diamond for his "exceptional artistic achievements as well as his philanthropic work, which has included many generous charitable donations over the years," according to a press release announcing the event. The gala will take place three days before the 51st annual Grammy Awards, which will be held at the Staples Center in Los Angeles on February 8.
