Gavin Rossdale hit the stage at KROQ's 23rd Annual Almost Acoustic Christmas Show on Saturday night in Los Angeles. While performing his hit song, "Glycerine," Gavin was joined by a very special guest … his wife, Gwen Stefani! The rock duo, who hasn't performed together in about a decade, met 17 years ago back in 1995 at this very same event. We're feeling pretty nostalgic right now, especially since Gwen and Gavin look almost exactly the same as they did in the '90s! Do you agree? Plus, Miley Cyrus sported a rather daring ensemble over the weekend during Israeli electronica DJ Borgore's Christmas Creampies concert in L.A., and we're taking a look at some of last week's wackiest getups worn by stars like Corey Feldman and Vivienne Westwood. What were they thinking?!
