Find out what the biggest stars of the '90s were up to with throwback photos from Hollywood's bygone era

Hollywood’s A-listers were out and about 34 years ago this week!

In late September 1990, Patrick Dempsey, Winona Ryder and Johnny Depp attended the premiere of Pacific Heights in Los Angeles, while in New York City Sinéad O'Connor made an appearance on Saturday Night Live — but not the one you're thinking of — alongside guest host Kyle MacLachlan. In London, glamazons Princess Diana and Joan Collins had a close encounter, and MC Hammer took his "Hammer pants" on the road.
