Very tenuous connections for me but here goes
I once took a phone call from our old company patron Loyd Grossman and still asked "who's calling please?". He visited the office a few times.
My best friend from high school was in Eastenders, the original celebrity love island and small parts in a handful of Hollywood movies (recently Maleficent 2), she had a lead role in a Sky One series. I am still in touch with her and we had coffee just before the lockdown, where I tried not to fangirl. I partied a couple of times with her when we were young and met a few footballers.
My husband's aunt au paired for Barbra Streisand and Liberace
My auntie au paired for the Duke of Wellington and played tennis with Princess Diana before she married Charles

I am friends with an Indie Band member's mum on facebook and we chat all the time, we met at a gig.
The Oasis Gallagher brothers attended the school I worked in for 12 years and there was a lot of memorabilia in the archives. I never could convince them to come and visit us but Liam replied to my tweet once.
My friend Tracy was responsible for getting Rage Against the Machine to number one in order to block X Factor always getting the christmas record. They put on a free gig after where she was invited on to the stage and presented a massive cheque for Shelter from the proceeds.
I bought some second hand furniture off Annabelle Apsion who was Monica in Shameless and in now in call the midwife. She was very Luvvie (but a nice lady!)

My husband was a cab driver and he picked up a few people in his cab, mostly football folk like Sir Alex Ferguson but a couple of pop stars e.g. atomic kitten
So yeah, most of my links are second hand! But some good ones.
