Bold a portion of concatenated string

Is there a way to bold a portion of a concatenated string, i.e. I have a cell
containing ="let's bold "&A3

Can I bold just the text from cell A3?

Formulas don't support that kind of character by character formatting (and
neither do numbers).

Can you use two cells?
