Laura June Nolan cheered when Matthew Denis Russell MacNabb finally ended a two-week relationship in record time — 4.1 seconds.

“She was playing him,” said Nolan, who was rooting for MacNabb, her fellow Irishman, on “Love Island UK,” season 7, which she watched nightly with her neighbor during the summer of 2021.

“He was really nice and down to earth,” Nolan, now 32, said. “He was witty. He was brilliant.”

MacNabb, 31, a strategic marketing consultant in Dublin, who received a law degree and M.B.A. from Ulster University in Northern Ireland, entered Casa Amor in Mallorca, Spain, on Day 29 of the show’s taping, and exited Day 45. He quickly became a fan favorite.

“Oh, he is lovely, isn’t he?” she recalled thinking after MacNabb returned to Ireland and posted a photo of himself hiking in the mountains with his then-6-year-old niece on Instagram. “Everyone was saying it. It wasn’t only myself, it wasn’t only my friend. It was the whole country.”

In November 2021, Nolan, a professional dancer then in her second season of “Dancing With the Stars Ireland” (“D.W.T.S.”), said she was “absolutely delighted” when MacNabb joined the show as her partner, but reined in her feelings.

“I have to do my job,” said Nolan, a world champion ballroom dancer.
