Coleen Mendoza is the older sister of Maine Mendoza, a.k.a "Yaya Dub". Some netizens call her as "Ate Dub"
And by these photos, we can tell that beauty and brains run in the family. The two seem very close, with a tight sister bond.
Maine graduated from Culinary Arts, while Coleen holds a degree in Accountancy.
Both of them are stunning and beautiful, but one advantage of Coleen over Maine is that she already met Alden even before Maine and Alden met.
