Rumer Willis is sharing a bump update with her sister by her side.

The 34-year-old daughter of Bruce Willis, 67, and Demi Moore, 60, posed with sister Scout Willis in matching sweatsuits in a mirror selfie shared Monday afternoon on her Instagram Story.

"Truly the only thing I've been wearing my whole pregnancy," the mom-to-be wrote, tagging clothing brand Bleusalt as she and Scout, 31, posed in burnt orange sweatsuit sets.

Rumer struck a similar pose in a photo with sister Tallulah, who turns 29 later this week, last month after first sharing her exciting pregnancy news.

The House Bunny actress and boyfriend Derek Richard Thomas announced last month that they're expecting their first baby together.
