The Victoria's Secret model took to her twitter page to post a black and white pic of her adorable baby Dixie Pearl to her followers at the weekend.
After uploading the image, Lily tweeted: ''Glad everyone liked our family pic :) she's our angel! (sic)''
Lily gave birth to the tot on June 21 and in the past few weeks she has been hitting the gym hard so she can get back into top shape and return to work for the underwear giant.
She wrote on twitter last week: ''Another amazing workout!!! Here I come @VictoriasSecret ;) (sic)''
Dixie Pearl is the first child for Lily, 26, and Kings Of Leon frontman Caleb, 30, and it seems the rocker is loving every minute of parenthood so far.
A source recently told Us Weekly magazine: ''They are so happy. The baby is adorable and healthy ... Caleb seems to really be enjoying fatherhood.''
The couple married at San Ysidro Ranch in Montecito, California, in May 2011 after dating for more than two years.
Caleb's bandmate and brother, Nathan, 33, and his singer/songwriter wife, Jessie Baylin, 28, are expecting their first child this December.
