Ava would be interesting. I, for one, am down for collaborations with celebs, but at the same time, I think it’s more advantageous to go with a celebrity with lots of established brands that could make the collaboration more appealing for non-fans.
I would love to see Rihanna collaborate instead. Rihanna has Fenty Beauty, which is an iconic makeup line with some incredible products that would look bomb on all Sims, she’s got her lingerie/lounge wear line which would be perfect for a Luxury Suite stuff pack (I think that’s what that pack was called in TS3), AND Fenty Skin which might work for the self care/skin care stuff pack EA pitched. I definetly feel like she might be too A-List to collab, but stranger things have happened.
In terms of a minor collab that’s just music and maybe merch(???), I would love to hear Miss Dua Lipa singing some Simlish.
