Jessica Simpson's daughter and best friend CaCee Cobb's baby are friends as well.

The 34-year-old designer shared an adorable photo of 3-year-old daughter Maxwell holding Cobb's 2-month-old infant daughter Wilder on Instagram.

"Maxwell and Wilder - a dream come true for me and @caceecobb #DoubleBFF," she captioned the picture.

Cobb is Simpson's former personal assistant, and the pair have been close friends for years. The designer was a bridesmaid in Cobb's wedding to former Scrubs actor Donald Faison, and is godmother to Wilder.

Simpson and husband Eric Johnson married in July 2014, and are also parents to son Ace, who turns two years old June 30. Cobb and Faison wed in December 2012, and welcomed their first child, son Rocco, in August 2013.
