Christina Aguilera can add another engagement ring to her jewelry collection!
"The Voice" coach -- who got engaged on Valentine's Day to longtime love Matt Rutler -- showed off her new ring via Twitter on Friday.
"He asked and I said ..." she posted, along with a photo of the two holding hands -- with her huge rock on display.
The singer and her now-fiance first met on the set of "Burlesque" back in 2010 ... while Xtina was still going through a divorce with ex-hubby Jordan Bratman (below).
Both of the rings are giant -- Rutler's engagement bling has a much more vintage feel to it, while her ring from Bratman definitely had a more modern look.
