Danny & Marie Osmond: A Couple or Brother and Sister??  

Normally I would say yes, but you must remember they are celebrities. Also they are know for proformances as a duo. I remember the Donn & Marie show. I used to watch it all the time growing up. I even had the Donny & Marie doll. Although they are adults they still have many, many fans. They have done things seperately...Donny became a singer, & a game show host for a while....Marie makes these porclin dolls that are collectables & most recently she was on Dancing with the Stars....but when it comes down to it they are mostly known(and famous for)they acts together as a duo.

Like the last poster said, I think it comes down to the fact that they are famous as a duo. They have fans that love them together as they remember them when they were younger. They want to recapture the great memories Donny and Marie brought them as children/young adults.
Some families stay close. Donny and Marie have about a million brothers and sisters. Ok, not a million, but they have a really big family and are said to all be very close.

To add to the last post too, Donny Osmond and Marie Osmond both had seperate careers during I think the 80's and 90's. Both Donny and Marie had their own (I believe successful) albums released seperately.
I am not old enough to have grown up with 'The Donny and Marie Show', but I do remember the albums they released each on their own. I remember there was a few songs from Marie's album and one from Donnie's that I liked and all of them played seperately on the radio a lot.

I think since I am not old enough to have 'Donny and Marie Show' memories I have more memories of them seperately, since they had seperate careers when I was growing up.

Now about Woody Allen and his adopted daughter. Well, that is just wrong, even if they weren't related. Now you can be close to your family without being that close. It is good to be close with your family, but wrong to be that close.

you know I kind of got that question in my head watching them together but it is hard to say, I guess it is possible for them be to be close but they defenatly act like a married couple.
