According to W‘s resident (and Twitter’s favorite) astrologers, the Astro Poets, 2019 is going to be a big one for Aries—and one full of surprises, from career changes to opportunities to reveal their true selves. Luckily, Aries are also some of the toughest (and most optimistic) bunch around—and one well worth appreciating this week in honor of the official start of their season, just a day after the first day of spring. Among those about to feel a surge of that Aries fire are Reese Witherspoon—who’ll no doubt serve up some surprises in Big Little Lies season 2—as well as Mariah Carey, Kristen Stewart, and Saoirse Ronan. Some have even already gotten a heard start on that career change—the most notable of which being, of course, Lady Gaga, star of A Star Is Born. (Though it looks like Elle Fanning is about to follow suit, finally living out her dreams of becoming a pop star in her next film, the musical Teen Spirit.) See which who else is set to heat things up this spring by revisiting their best portraits in W over the years, here.
