"Você está tão quente!"
Here's a breakdown:
* Você: You (informal, used with someone you know well)
* está: are (present tense of "estar")
* tão: so
* quente: hot
Important note: While this phrase is widely understood, it can be considered quite direct and potentially flirtatious.
Here are some alternative expressions, depending on the context:
* "Você é muito atraente." (You are very attractive) - This is a more formal and polite way to express attraction.
* "Você é gostoso(a)." (You are handsome/beautiful) - This is a common phrase used in a more informal setting.
* "Estou impressionado(a) com você." (I am impressed by you) - This is a more subtle way to express attraction.
Remember to choose the phrase that best suits the situation and your relationship with the person you are talking to.
