Jennifer Hudson's gala appearance

Jennifer Hudson will make her first public appearance since the tragic deaths of her mother, brother and nephew at the MusiCares Person of the Year gala in February.

The 27-year-old star - who has been in hiding since mom Darnell Donerson Hudson, sibling Jason Hudson and seven-year-old nephew Julian King were shot in October - will perform a selection of Neil Diamond songs at the event, to be held at the Los Angeles Convention Center.

Other stars to grace the stage at the concert on February 6 include Coldplay, the Foo Fighters, Josh Groban and Tim McGraw ahead of the 51st annual Grammy Awards in Los Angeles' Staples Center on February 8.

Jennifer is said to be ready to get her life and career back on track following the tragedy.

Earlier this month, she was due to shoot a rescheduled video for her new single 'If It Isn't Love' - which was originally set to happen around the time of the deaths.

However, Jennifer pulled out of filming the promo amid reports she was still too emotionally distressed about the murders.

Jennifer's brother-in-law William Balfour - the estranged husband of Jennifer's sister Julia - has been charged with three counts of first-degree murder and one count of home invasion.
