It was announced on Sunday (October 14) that the actor and singer had broken up after nine years of marriage and that the split was "amicable".
Danielle's father Don Spencer, who was once a children's television presenter, told Yahoo's WHO: "I love them both and am naturally sad as any father would be in this situation."
Damian Whitewood, Spencer's dance partner on Dancing with the Stars, has also spoken out about the situation, after rumours spread that he was the reason for the split between Crowe and Spencer.
He took to his Twitter account to say: "'Wow! Sad and crazy news day full of rumours I didn't ask for!"
While the showbiz world was taken by surprise by the split, close friends of Danielle were reportedly not as shocked, saying that the couple's relationship had been stretched for months and she had to be the one to "pull the plug".
An apparent friend told the Daily Mail: "It's not surprising that she has reportedly found support in another man, although whether that's still on with Damian is something that Danielle is keeping pretty quiet about."
Russell Crowe is currently filming Darren Aronofsky's Noah alongside Emma Watson in New York.
