Taylor Swift gave Dakota Johnson some pretty sweet payback for appearing in her “Patient Zero” music video: the mega-star joined the Verity actress during her opening monologue.

Perhaps it was just a birthday present for Johnson, who turns 37 on Sunday. Either way, Swift came in to yuk it up with Johnson, who used her opening moment to wax on about dating musicians.

“I went through two very public, very lame breakups with two very awesome musicians,” Johnson said about what she’s been doing since the last time she hosted SNL. This is her third appearance on the NBC show.

“It’s not my fault, though,” Johnson continued. “Some people leave concerts with merch and I leave concerts with a two and a half year relationship.”

“But I have really good friends,” she continued. “They don’t judge me for dating these men. They’re actually really supportive.”
