It doesn't get much cuter than this!

Jamie Lynn Spears is celebrating the birthday of her second child, daughter Ivey!

The actress' mini-me turned a year old this week, and in honor of her big day, her mom threw her an adorable rainbow-themed party.

Jamie pulled out all the stops for the bash, decorating her home with unicorns, balloons and candy, and dressing Ivey (whom she shares with husband Jamie Watson) in a cute rainbow dress and white headband.

Ivey's older sister, 10-year-old Maddie, was right by her side, singing "Happy Birthday" in a video Jamie shared that's fittingly set to "Somewhere Over the Rainbow."

It appears Jamie's sister, Britney Spears, was unable to attend the party. ET reported earlier this month that the singer checked herself into a health facility to help her cope with the stress she's dealing with over her father, Jamie Spears', health crisis.

ET learned that Britney temporarily left the facility on Thursday, in order to get her hair done at a local salon.
