Welch, 28, told the magazine: "I know it sounds a cliche, but she's good to talk to about boys. She knows her stuff."
The Londoner revealed she was with a group of celebrity A-listers at 25-year-old Swift's apartment when she turned to them for help with boy trouble.
She said: "Lena Dunham was there, and Spike Jonze and Reese Witherspoon and Zooey Deschanel, eating pizza, talking about boys. I'd already asked loads of taxi drivers and everyone else I'd met (for advice) so I thought why not Taylor Swift and Spike Jonze too?"
The singer opened up about feeling low as she struggled with boy trouble, and revealed she is now dating someone new - a fashion photographer she met in her local park.
Taylor is really a down to earth girl in real life. Consider all the friends she has and it sounds like real friendship and people adore her. None of her friends talking trash about her and they keep haging out.
