How about getting your friend tickets to a Lady Gaga concert that she/he can attend with a friend or loved one? Alternatively, you could get your friend some Lady Gaga merchandise such as a t-shirt or hoodie. Another option would be to create a personalized Lady Gaga playlist, with all of your friend's favorite songs by the singer, loaded onto a portable device such as an iPod or USB stick. Finally, you could get your friend a Lady Gaga biography or coffee table book that discusses her life, career and artistic vision. I hope these suggestions help!
Or you can get her/him a star map with the date when she/he was born.
