Lady Gaga is being accused of creative plagiarism again after her VMAs performance -- by Kelly Osbourne!

Osbourne Tweeted about Gaga doing the show as her male alter ego, Jo Calderone:

    "i love lady gaga but i wish she would start giving credit where credit is due! example... 1984 PEOPLE!"

Osbourne's link goes to the Eurythmics' 1984 Grammy performance -- when lead singer Annie Lennox performed as a very similar looking man (see video below.)

Earlier this year, Gaga was accused of ripping off her mermaid-in-a-wheelchair bit from another big star of the 80s -- Bette Midler. She's also come under fire for similarities to Madonna, and she was sued this month by a Chicago songwriter for plagiarism with her song "Judas."
