Tbf i wouldn't be surprised considering it's also kinda a 'viewing party' on top of his b-day if the celebs wouldn't want to be around 'ordinary' ppl outside of his family or so in case of leaks and such but other than promising to buy dinner i dk if they've 'caught up' enough to spend time together again or so lol, tho her showing up with 3 other 'beauties' prolly would've been bad too
