Edyta Sliwinska and Alec Mazo's tiny dancer has arrived! The former Dancing With the Stars pros welcomed their first child together on Jan. 4. The new parents shared the special announcement -- and an adorable baby photo! -- on Twitter Thursday, Jan. 9.
"Our bundle of joy, born on Jan 4th!" Sliwinska, 32, captioned the picture. "We are in love and as happy as can be!!!" In the snapshot, the new mom cradles her infant in her arms while posing in front of a fireplace.
The photo also reveals Sliwinska's amazing post-baby body. The professional ballroom dancer looks gorgeous -- and already very slim -- while posing in a cleavage-baring, short white dress.
Sliwinska and Mazo, 35, who wed in September 2007, announced they were expecting their first child together back in October on Twitter. "Thank you! Thank you! Thank you! I'm overwhelmed with all your wonderful messages & congratulations," Sliwinska tweeted at the time. "You are the best . . . Thank you! Can't wait to be a mommy."
Over the holidays, the couple enjoyed their final days as a family of two. "Reminiscing on the last year with only 2 of us," Sliwinska tweeted Dec. 31. "Happy New Year Everyone!"
