Bride-to-be Cheryl Hines has turned to her future stepdaughter, actress Kathleen 'kick' Kennedy, for help as she makes last-minute wedding preparations before exchanging vows with Robert F. Kennedy, Jr. next month (02-03Aug14).

The Curb Your Enthusiasm star, who became engaged to the attorney in April (14), will become a member of America's famous Kennedy clan on 2 August (14), when they tie the knot at the family's estate in Hyannis Port, Massachusetts.

However, the groom's daughter reveals the couple has yet to make a few decisions about the big day - including what dress Hines will wear - so she is doing what she can to help.

She tells the New York Daily News the wedding will be a "secret affair, very private", but adds, "I'm trying to help the best I can. It's a fun wedding with two very fun people who aren't necessarily always very organised. So I try to be there to pull everything together when I can."

And Kennedy insists she cannot wait to officially welcome Hines into her family: "I always loved Curb. It's great (that they're marrying). I love Cheryl, and I'm excited for our new family."
