Newly announced Eurovision host Angela Scanlon once discovered she has a very famous relative.

The television presenter, who is replacing Scott Mills in the UK's Eurovision commentary team this year, is actually a distant relative of actor and comedian Stephen Mangan.

The pair are third cousins once removed, a revelation that emerged on Angela's programme Ask Me Anything a few years ago, reports the Mirror.

Episodes star Stephen was a guest on the show when Angela revealed: "So I heard, like, whispers that maybe we were related. Then I thought, you know, my dad's from Mayo. Maybe it was just one of those, 'Ah, he's on telly, so are you' and you're both from Mayo, kind of..."

She then read aloud a note, telling Stephen: "So this message is from my dad's Auntie Katie's daughter. 'Mary Mangan,' she says, 'Mine and Phelim - that's my dad's grandmother - was a sister to Michael Mangan'."

"My great grandfather!" Stephen exclaimed.

"Your great-grandfather?" asked Angela, looking stunned. "So that makes us?"

"Third cousins once removed!" Stephen announced.

It has just been confirmed that Angela will form part of the UK's Eurovision commentary line-up this year, alongside Rylan Clark and Graham Norton. She will join Rylan at the Wiener Stadthalle arena in Vienna to steer viewers through the competition's semi-finals.

She takes over from Scott Mills, who was axed by the BBC earlier this year following historical allegations concerning his personal conduct.

"It feels like joining the greatest party on earth - equal parts thrilling and terrifying!" she said of her new role.

The former Strictly Come Dancing contestant continued: "I grew up watching the Eurovision Song Contest with my three sisters, making very serious (and wildly biased) scorecards from the couch, so to now be part of it - especially in its 70th year - is genuinely surreal.

"It's one of those shows that's always been there, evolving but never losing its magic or madness.

"I've been lucky enough to dip my toe into the Eurovision world before, so it feels great to be doing it again, just with higher heels and a few more sequins!"

The semi-finals of the Eurovision Song Contest will air on Tuesday May 12 and Thursday May 14 at 8pm on BBC iPlayer and BBC One.
