J Lo 45, caught stars Iggy Azalea and Rita Ora’s performance at Black Widow as part of a pre-MTV Video Music Awards concert sponsored by Time Warner Cable and Lifeboat. She totally caught Iggy’s unfortunate fall during her “Fancy” performance. You’ll never guess how Jennifer Lopez captioned her pic…
