son.Taylor Swift couldn’t hide her smile as she left a recording studio in New York with her smitten new boyfriend Matty Healy after a night of partying.

Taylor Swift had her number one fan by her side at a recording studio session on Monday night.

The singer’s beau Matty Healy was seen leaving the Electric Lady recording studio in New York with the popstar after a spot of late night music-making and partying.

Taylor couldn’t hide her smile as she strolled to her car dressed in a low-key look of a black mini skirt and a purple NYU sweater.

She added a glam face of makeup for her night in the recording studio.

The couple were joined by some of Taylor’s close friends for a party at the studio, with Florence Welch, Margaret Qualley and her boyfriend Jack Antonoff, who is a long-time collaborator of Taylor’s, also seen leaving the venue.

Kendrick Lamar, who previously worked with Taylor on her hit track Bad Blood, Girls actor Christopher Abbott and filMMAker and actor Adam Goldberg were also among the party-goers.

Matty and Taylor put any questions about their relationship to bed last week when they were spotted showing off some major PDA on a date.

The two had dropped by New York City’s Casa Cipriani with Antonoff — who has been one of Taylor’s biggest producers and collaborators since they first worked together shortly before she began work on her 1989 album — and his girlfriend, the actress Qualley.

Taylor and Matty were separated by security from other patrons while ‘cuddling and kissing’ in a lounge at the hot spot, a witness told Page Six.

Matty has lately been spotted several times in the audience at stops for Taylor’s blockbuster Eras Tour.
