A very pregnant Beyoncé stripped down to a bikini top and long skirt during her Beverly Hills baby shower Saturday — with no qualms about showing off her twin-sized baby bump.

The 35-year-old mega-celebrity, who has yet to reveal the gender or due date of the babies-to-be, has decorated her massive belly with a large henna tattoo, as these photos from her star-studded shower show.

Guests included La La Anthony and tennis goddess Serena Williams, who is also pregnant.

Beyoncé’s ex-Destiny’s Child bandmates, Kelly Rowland and Michelle Williams, also attended.

Proud mom Tina Knowles Lawson led guests in hollering “Happy Carter push party!”  a shout-out to Beyoncé’s married name: Mrs. Shawn “Jay-Z” Carter.
