Selena Gomez offered her fans a Rare Beauty tutorial on her Instagram timeline while flashing her gorgeous marquise diamond engagement ring.

Selena Gomez officially has engagement ring syndrome. She can't stop posting about her stunning engagement ring, and it's becoming a brand new fixture in the videos and photos posted to her social media—not that the fans of her and Benny Blanco's adorable relationship seem to find.

Actress-singer Selena Gomez and Benny Blanco may just have announced their engagement but with Christmas around the corner the pair have no plans to spend the holiday in the kitchen together. Selena recently stepped out to The Hollywood Reporter's Annual Women in Entertainment Gala to pick up the award for Equity in Entertainment.
