This week's biggest pop culture moment is, without a doubt, the birth of Khloé Kardashian's first baby, plus all of the drama surrounding her boyfriend Tristan Thompson's cheating allegations.
But another duo got our attention this week: Paris Hilton and Nicole Richie. The former Simple Life co-stars, and IRL BFFs, had one unexpected reunion at the fourth annual Daily Front Row Fashion Awards Los Angeles ceremony, where they came together for one epic shot you'll have to scroll down to see. Jeremy Scott, Paris Jackson, Chrissy Teigen, and John Legend were also there, but it's Hilton and Richie that stole the show.

In New York, Liv Tyler and Bel Powley headed to the Alley Cat Amateur Theater at The Beekman to celebrate their new film together, Wildling. It's about a young woman who transforms into a werewolf, so you'll want some extra popcorn and maybe a spiked iced tea for that. Also in Manhattan, Joan Smalls celebrated the opening of the Nordstrom men's store in a posh white suit.
