Martin and Kathleen apparently did not want their youngest child to marry the actor but are relieved they have parted ways after five years, reported Radar Online.
"Obviously, Martin and Kathleen are sad that Katie is having to go through all this emotional turmoil and that she is going to be a single parent, but it's not like she is going to have to go it alone and she certainly won't have any financial hardship to worry about.
"Both Martin and Kathleen had very strong reservations about Katie marrying Tom, but she was an adult and they obviously couldn't stop her from following her heart. It's been tough for them over the past five years to watch Katie be controlled by Tom and they really felt that they had lost their daughter to some extent," a source said.
