Matty Healy‘s mom caught a lot of heat for her recent comments about Taylor Swift … and, it might be getting to her — because she was just spotted crying on a city sidewalk.

The singer-songwriter was seen hugging his mother, Denise Welch, outside a high-priced restaurant in West Hollywood on Thursday before sitting on the curb and chatting with her while she dabbed her eyes with a tissue.

The two seem deep in a difficult conversation … with Healy appearing animated at one point while his mom was shedding tears.

You’ll recall, Welch recently pissed off a ton of Swifties when she knocked Taylor on Andy Cohen‘s hit show “Watch What Happens Live” … saying she was glad she would never be her mother-in-law.

She tried to walk back the comments on the program … but, the damage was done — foot securely lodged in mouth.

Healy and Swift have taken shots at each other in the past years … multiple songs on “The Tortured Poets Department” are about their short-lived romance — and, Healy hit out at Taylor by saying he wouldn’t write songs about “casual flings.”
