The tweet went viral as people began making the connection that Alfie and Lily are related, and discovered the song she wrote about him, aptly titled "Alfie."
Here are just some of the lyrics:
“Oh, Alfie get up it's a brand new day,
I just can't sit back and watch you waste your life away,
You need to get a job because the bills need to get paid,
Get off your lazy arse,
Alfie, please use your brain,
Surely there's some walls out there that you can go and spray,
I'm feeling guilty if I leading you astray,
Now, how the hell do you ever expect that you'll get laid,
When all you do is stay and play on your computer games?”
She also, as any sibling would, revealed a rather embarrassing story in her memoir from when they were kids. Alfi, upon meeting Princess Diana at the premiere of their mother Alison Owen's film Hear My Song in 1991, had to tearfully tell the royal, "my willy is caught in my zip."
Yikes. At least Alfie seems to have proven Lily wrong since the 2006 song.
