Celine Dion put on a brave face at the viewing of husband Rene Angelil, personally sharing a moment with almost every mourner.

The viewing was held at the Notre-Dame Basilica in Montreal, where the couple married in 1994.

Celine sometimes tearfully stood by Rene's open casket, accepting condolences from the public. There's a huge line wrapped around the cathedral.

The funeral is set for Friday.
