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.

1975 frontman Matty followed close behind, placing a protective hand on her back.

Taylor showed off her tanned legs in her tiny mini skirt, and kept her ensemble casual with a pair of tennis shoes.

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.

Last week, he was even seen standing near the Blank Space singer’s father, suggesting their relationship is on the upswing.

The 1975 singer has even been performing occasionally on the tour.

Taylor’s friend Phoebe Bridgers has been opening for her on several stops, and she has invited Matty on stage to accompany her on guitar.

However, he hasn’t had any direct musical collaborations with Taylor on the tour.

Healy co-founded his band The 1975 way back in 2002, when he would have only been around 13.

Beginning with the band’s 2013 self-titled debut, the group has managed to top the UK charts several times, while scoring in the top 10 on the Billboard 200 albums chart.
