Beyonce Knowles and her rapper husband Jay-Z made a surprise appearance at the Weinstein pre-Oscars party at the Montage Beverly Hills on Saturday night, February 25. The powerhouse couple surely stole the spotlight during their glamorous night out after making an entrance with multiple security guards.

The heavily pregnant diva, who is expecting twins, glammed up in a baby bump-hugging turquoise dress at the Harvey Weinstein soiree that was hosted by Heineken and Grey Goose. She arranged her long honey locks in loose waves. Enjoying her pregnancy, the "Formation" hitmaker was all smiles at the festivities before the Oscars.

Her rapper husband also looked dapper as usual in a black suit with a camouflage-printed shirt underneath at the star-studded party. Jay-Z seemed to be having a good time as well. The 47-year-old rapper was seen smiling from ear-to-ear as he sat next to his stunning wife.

Beyonce and Jay-Z enjoyed the live performance of Corbin Bleu, Cynthia Erivo and Chris Jackson on the joyful night. The trio actually already wrapped up a performance of songs from upcoming film adaptation of the Tony-winning musical "In the Heights" when the couple arrived, but Harvey asked them to restart it so that the parents of Blue Ivy could see the entire performance.

Also in attendance at the annual celebration were Oscar-nominated "Lion" co-stars Nicole Kidman and Dev patel. Other celebrities attending the glamorous bash that night were Nicole Scherzinger, Lin-Manuel Miranda, Tracee Ellis Ross and Rachel Roy, whom many Beyhive believed was the infamous "Becky with the good hair."
