Smokey, who was among the first celebrities to offer up a tribute to the Miss You Like Crazy singer following her death on New Year's Eve (31Dec15), was the first star to speak at the West Angeles Church of God in Christ memorial service.

He told fellow mourners, "I feel so blessed to have called you my friend, my buddy, my confidante."

Lionel Richie, songwriter David Foster and actress Angela Bassett were spotted at the service too, as was Chaka Khan, who performed at the event.

Stevie Wonder was also among those who performed a tribute to Cole, who died from congestive heart failure at the age of 65. The singer's body will be laid to rest alongside her parents, sister and brother at Forest Lawn Memorial Park in Glendale, California.
