Feign ignorance. (as in “Who’s [name]Taylor[/name] [name]Hanson[/name]?”)
I would probably use them but the ignorance would be real. [name]Love[/name] [name]Penelope[/name] and [name]Viggo[/name]!
Not many people would know the name of [name]Taylor[/name] [name]Hanson[/name]'s children so I don’t see why you can’t use them if you love them. It does seem like celebrity children have a pecking order so personally I wouldn’t use a more commonly known sibset like [name]Jolie[/name]-[name]Pitt[/name]. I voted for the option “depends on the celebrity”.
Haha, I love the advice to feign ignorance! That would be totally hilarious in my case! 
I don’t know who [name]Taylor[/name] [name]Hanson[/name] is.
I’ve only heard the names of a handful of really crazy celebrity baby names.
[name]Penelope[/name] is a lovely name that’s rising in popularity, so using it couldn’t possibly make people wonder unless you have a giant mural of this [name]Taylor[/name] person on your wall or something.
And as you say, it’s unlikely you’ll even use the second name, but if you did it would be at least 5 years from now I’d imagine and they likely won’t even be famous anymore. I wouldn’t worry about it.
To answer the broader question, I wouldn’t purposely use a celebrity’s sibset, no. But if I chose names I loved and they happened to be shared by a celebrity, I wouldn’t really care unless they were exceptionally uncommon.
