Byul and Wonder Girls' Sun were spotted out and about together. 

The two soon-to-be moms were seen shopping for items and supplies for their babies at the 'Seoul Baby Fair 2013' at SETEC. It was obvious that Byul and Sun were on a mission as mothers, not as celebrities, as they tried to blend in, wearing plain clothes.

Netizens commented, "I still can't believe that Sun is married," "Both are from JYP Entertainment," "Only their stomachs are out," "Cute," and more.

Byul married HaHa last year at the end of November, and she's currently 7-months pregnant. Sun also made waves as one of the first idols of this generation to get wed. She married Korean-Canadian James Park in January of this year, and she's 4 months into her pregnancy.

Congratulations to both couples once again!
