Yes, it's called product placement. The actors aren't paid for it, the studio that makes the show is paid to feature the products.
The products you see in a program are paying to be there (character driving a new VW). If a celeb is drinking a red bull during an interview there is a chance they are being paid to drink it.
The celebrity isn't being paid, the production company for the show is.
Often, but more likely the show is a sponsor.
If you can see a trademark, chances are they paid them.
Watch NASCAR and you'll have your answer.
When celebrities drink a Red Bull or another brand-name drink while on television (not commercials), are they really being paid to advertise for those companies?
