Inside Matty Healy & Gabbriette Bechtel's fast-track to engagement

The 1975 frontman Matty Healy and model Gabbriette Bechtel are officially engaged, announcing their whirlwind romance's next chapter with a black diamond engagement ring.

An insider shared with PEOPLE that the couple, who started dating last fall, are deeply in love and thrilled to be engaged. Bechtel's unique ring, featuring a large black gem and pavé diamonds, perfectly reflects her unconventional and fun personality.

Healy's mother, Denise Welch, expressed her excitement and approval of Bechtel on the British talk show Loose Women, calling her "everything I would want in a daughter-in-law."

Bechtel announced the engagement on Instagram with photos from Charli XCX's show in Brooklyn, where the couple celebrated with friends.

This engagement follows Healy's brief fling with Taylor Swift and Bechtel's previous relationship with model Levi Dylan. Bechtel had revealed in a past interview that she and Healy had been trying to connect for years before finally starting their relationship.
