In a series of snaps, the pop superstar, 35, rocked a form-fitting, long-sleeved purple gown with floral frames and set to The Isley Brothers’ song Pop That Thang.
In another set of shots, the Bootylicious hitmaker, 35, flaunted her accessories, including earrings, wedge heels and blue ring.
The singer’s husband, rap superstar Jay Z, and their 5-year-old daughter Blue Ivy also made appearances in her online slide show.
Last month, the soon-to-be mom-of-multiples shared maternity snaps after attending an event to support mom Tina Lawson and Tina’s Angels, the mentorship group founded by her mother.
Also in March, the Grammy Award-winning singer hinted that her twins might be boys.
Earlier in March, the Formation hitmaker posted photos with Blue at the Hollywood premiere of Beauty and the Beast.
The former Destiny’s Child frontwoman also stepped out at the Weinstein Company and Grey Goose’s party for the Academy Award-nominated film Lion on Feb. 25.
Also last month, the A-listers attended the NBA All-Star game in New Orleans with Blue.
In early February, the Grammy Award-winning singer and the rapper shocked fans and announced they are expecting twins.
“We would like to share our love and happiness. We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. – The Carters,” the expectant mama captioned the image cradling her bare baby bump amid a sea of flowers.
This is the couple’s third pregnancy. The A-listers – who were wed in 2008 – were expecting a baby prior to Blue Ivy, but the singer suffered a miscarriage.
