Chrissy Teigen‘s daring maternity wardrobe just keeps getting racier!

The pregnant supermodel went braless in a lacy top and black high-rise leggings to attend Lady Gaga‘s star-studded 30th birthday party on March 26, though the duster coat she used to cover her boobs didn’t do that good of a job.

The 30-year-old, who was accompanied by hubby John Legend, suffered a nip slip outside the bash, and had to hold down the lapels of the jacket in order not to flash any more of the paparazzi.

Chrissy has been quite experimental with her maternity style, wearing anything from a sheer crop top to an underboob-flaunting gown!
