Last week, Billie confirmed that she is expecting her first child with boyfriend Greg Shepherd, saying they are "so excited".
There's no rest for the wicked, however, as expectant mum Billie has spent the afternoon cleaning her house from top to bottom.
Billie still found time to pose for a picture though, and is wearing a new black all-in-one with star detail, which cleverly concealed her growing bump.
Sharing the snap on Twitter, Billie told her followers: "Doing housework in my @SouthBSwim onesie ..."
After confirming her exciting news, Billie was inundated with messages of congratulations from her TOWIE co-stars.
Ricky Rayment tweeted: "@BillieFaiers @Gregshepherd_ congratulations to u both!! Amazing news xxx"
Lauren Pope also sent Billie an emoticon of a baby's face, adding: "@BillieFaiers Congratulations!!!"
