You oughta know that this happened at Monday's concert at L.A.'s Staples Center.
So far, everyone from Kobe Bryant to Julia Roberts has made a cameo appearance on Taylor Swift's 1989 World Tour (including her infamous girl squad — because duh). At her L.A. concert last night, Swift added to her long list of increasingly random-seeming guests (Matt LeBlanc? OK.) by inviting Ellen DeGeneres and Alanis Morissette to join her onstage at the Staples Center.

Both Morissette (who dueted on "You Oughta Know" with Calvin Harris' main boo thang) and DeGeneres dressed for the occasion — meaning they matched the pop star in similarly skintight outfits.
Morissette introduced a whole new generation to her angsty ballad while clad in leather pants, chunky black boots and a black blazer, standing alongside Swift, who wore a black leather jumpsuit.

But the real showstopper of the evening was DeGeneres, who made her glittering onstage debut in a sequined jumpsuit, which she paired with a fringed, hula-esque tutu skirt. The Ellen host and lifestyle-brand pioneer topped the sparkly look like any fashionista would — with plain white sneakers, of course.

Though it's a tough call, we'd have to say that, in this case, DeGeneres really wore it best.
