What do you mean by actress and plain boyfriend?

A female star's amateur boyfriend is called an amateur boyfriend because his boyfriend is the same as most people, an ordinary person, neither a online celebrity nor a star, and even one who has no name on the Internet. Because if a female star has an amateur boyfriend, her life is not easily disturbed, and she can also protect her loved ones from being attacked by life on the Internet. Therefore, many stars are divorced by amateurs, no matter they are male or female stars.
