Is it normal for a boyfriend and girlfriend to never hang out alone?

Lets say you had been dating for 3 years. The boyfriend has several male and female friends he usually hangs out with. The friends are also friends of the girlfriend. But for some apparent reason when you hang out with your girlfriend lets say go to the movies or go to another city to be with your friends for any reason. You always either bring your girlfriend with you cause she always want to go with you wherever you go, the boyfriend barely hang out with his buddies by himself, the girlfriend always tag along, even if the girlfriend know her boyfriend friends too or the other option your friend always go with the couple, like if it was the third wheel. Lets say the boyfriend is a very public figure (movie star), he is chased by paparazzis whenever he is caught with his girlfriend and the friend and the girlfriend is nto in the public life or entertainmetn business, was a restaurant waitress but enjoy to be seen and bring attention and the photos are always like I described above. Also the girlfriend is with him everywhere he goes, like he can't catch a break hehe!!! If he has to work oversees for months, she goes with him, if he hangs out with his buddies, she also is there, if he goes with the movies with her, he brings his friends with them. If he attends publci events of his profession he brings her but also he brings other people. Like he is never alone with her always people surrounding while he is with her.
