boyfriend fiancé definitely wasn't joking around when he got down on bended knee with THIS sparkling hunk of diamond!
We previously reported that Sofia had gotten engaged to her boyfriend, Nick Loeb, and was spotted rocking the HUGE engagement ring at a birthday party while in Mexico last night!
Check out Sofia's brand new bling (above)!!!
Gorgeous!! Not too shabby of a 40th birthday present, either! Ha!
We wish both Sofia and Nick the best as they prepare for their waltz down the aisle!!
