Whatever they're doing, it's working. Their debut single, ballad "I Do," which, like the docu-series, reveals the couple as deliriously and genuinely in love, hit #2 on the iTunes Pop Chart, and #6 on the overall chart within a few days. Now, leading up to the second episode of Ashlee + Evan, the pair are debuting their second single: "Paris."

Seductive and slinky, "Paris" is an R&B-inspired club ode to the city of lights, dripping with champagne and cinematic nostalgia. Simpson uses her soulful, throaty vocals, which have only improved over time, to frame a tangled-in-the-sheets weekend: "Naked in Paris, terrace, vintage in paradise/ On the velvet, helpless, let's play the games we bought tonight/ Don't forget the ice" over woozy, heart-beating production. The pair harmonize on the chorus, and Ross contributes to the picture: "Wearing your fur coat, hang your red dress soaking wet/ Plaza Antoinette, dancing round like Josephine Baker."

The pair have a delicious, easy chemistry, and honestly "Paris" was probably inspired by a real trip the pair took. We get it, you guys obsessed with each other! Just kidding, we can't get enough.

Building off of "I Do," "Paris" emphasizes that Simpson isn't an angsty teen anymore, but rather a mature, in-control artist, making music with the person she loves.
