In the series of snapshots, the Formation singer, 35, showcased her chic maternity style from Jessica Alba‘s 36th birthday on Apr. 28.
“Flashback to an MJ+Prince party, crystals and ruffles, and a screw mix by Derek Dixie,” she captioned the slideshow.
In one video — that featured Jackson’s hit Rock With You — the Grammy Award-winning singer rocked her $4,950 Any Old Iron rhinestone jacket.
In late April, Alba celebrated with many of her A-list friends at Los Angeles hotspot The Peppermint Club.
Last weekend, the twins mama-to-be and husband Jay Z celebrated their baby shower over the weekend, which was dubbed the “Carter Push Party.”
Guests arrived to the shower – which was held at a private residence in Beverly Hills that was once owned by Madonna – around 2 p.m. via limos on Saturday (May 20).
The A-listers are currently expecting twins. They are already parents to 5-year-old daughter Blue Ivy.
