Your attention-grabbing friend might be one who goes through life imagining it's a movie starring her. Starring means being the main character in a movie or play.
Starring is an adjective that's used when someone's at the center of things, like a concert starring a famous cellist. The Greek word aster became the English word star, which was first used to mean "to be featured in a play" in the 1820s. If you imagine a star shining brightly in the dark night sky, it's easy to see how starring came to mean "being the most important on the stage."
