AceShowbiz - On June 11, The 1975 lead singer, Matty Healy, 35, and model Gabbriette Bechtel, 26, made waves as they announced their engagement. The surprising revelation came as Bechtel shared stunning photos on social media, flaunting a striking black diamond engagement ring that matched her unique style.

This heartwarming update follows just nine months after the duo first sparked dating rumors with a public display of affection in New York City last September.

An insider told PEOPLE, "They've only dated since last fall, but Matty quickly fell in love with her. They've had a serious and intense relationship from day one."

Their whirlwind romance has been nothing short of extraordinary. Despite their brief courtship, both Matty and Gabbriette appear incredibly happy and deeply in love. The source added, "They're excited to be engaged. They're such a cool couple. They like to do things their way."

The couple's unconventional approach to their relationship is evident in Bechtel's engagement ring. The non-traditional piece is characterized by a large black gem surrounded by pavé diamonds, perfectly reflecting Bechtel's eclectic and fun-loving personality. "The engagement ring is so her - it's perfect. She's unconventional and fun," shared a source with PEOPLE. "They are both close with their families. Everyone is happy for them."

Healy's mother, actress and TV host Denise Welch, couldn't contain her excitement during a segment on British talk show "Loose Women". She said, "I obviously have known for a few weeks that Matty got engaged ... They went over to see their friends Charli [XCX] and George [Daniel] in New York [last night] and I woke up this morning to the fact they've put it on Instagram."

Welch beamed with joy, stating, "Instagram official ... he's got engaged to Gabriella Bechtel — Gabbriette she's known as. Black diamond; he had it made for her. I couldn't be more thrilled. We couldn't be happier - she is everything I would want in a daughter-in-law. I'm thrilled."

For those who have followed Healy's journey, it's a happy twist after his previously reported brief fling with superstar Taylor Swift came to an end last June. Prior to Healy, Bechtel was linked to model Levi Dylan, adding another layer of celebrity intrigue to their romance.

The sparks between Healy and Bechtel were ignited long before they officially started dating. Bechtel revealed to Homme Girls, "He came to L.A. and we've been in love ever since." Now, the couple is set to navigate their future together, embodying the modern romance with their unique bond and eclectic sense of style.
