She's not like I thought at all

[lilyyang]

She’s… Well, she’s not like I thought at all. She’s amazing.

Question: Is it okay to say the sentence above? Or should I add “what” after “like”? Or both are okay?

She’s not like what I thought at all.
=She’s not like I thought at all.

Thank you!!!

IMO, both are OK.

I agree, both seem ok. Not sure if one isn’t grammatically correct, but both sound ok to my ears
