Hours after Kevin Federline and his wife, Victoria Prince, welcomed their baby girl to the world, his two sons he shares with ex Britney Spears arrived to meet their little sister.

Victoria took to Instagram Thursday to post images of the sweet moments Sean Preston, 8, and Jayden, 7, laid eyes on the newborn earlier this month.

“#tbt almost three weeks ago! Jordan holding her little sister at the hospital, she’s not even a day old!” she said, referring to her 2-year-old daughter she shares with Kevin.
