Get ready for your heart to melt -- in the most festive way possible.
Rachel Bilson's daughter, Briar Rose, is doing up the holidays toddler-style.The O.C.alum took to Instagram to show off the evergreen her little girl thoughtfully picked out and decorated.
The itty bitty tree got its tiny branches covered in multicolored lights, shiny pink ornaments, red bows and candy canes.
"When you let your three year old pick out the tree.....?," the proud mom joked.
The 36-year-old actress rarely posts photos of her daughter on social media, though she did share a pic just two days ago of Briar and her cousin playing outside in Toronto, Ontario, in honor of Briar's aunt Kaylen Christensen's birthday.
Bilson shares Briar with her ex-fiancé, Hayden Christensen. The pair broke up earlier this fall.
Though she's notoriously private about her personal life -- she has yet to publicly speak out about the split, which made headlines in September -- last year, the Nashvilleguest star did gush to ET about her daughter, revealing that she's learned "patience" from her baby girl.
"It's just the most rewarding job in the world and it's the hardest job in the world, so I have so much respect for moms that do it on their own," she said.
