Alicia Silverstone is celebrating a major family milestone as her son, Bear Blu Jarecki, turns 15. The Clueless icon took to Instagram on Wednesday to share a deeply personal tribute to her only child, whom she shares with her ex-husband, musician Christopher Jarecki.

The post featured a nostalgic carousel of images, ranging from the moment she became a "newly minted mom" to recent snapshots of the teenager.

In the heartfelt caption, the 49-year-old actress expressed her amazement at the passage of time. "It’s Bear’s birthday today... 15 years with this human… I can’t believe it," she wrote.

The actress, long known for her advocacy of a natural lifestyle and attachment parenting, went on to describe motherhood as the "most incredible gift."

The shared photos offered fans a glimpse into Bear’s adventurous upbringing, including scenes of him climbing trees, practicing yoga, and sitting in the cockpit of an aircraft.

One particularly "wholesome" image showed a newborn Bear cradled in his mother's arms, while more recent snaps featured the duo enjoying a day at a waterfall.

Silverstone and Christopher Jarecki, who divorced in 2018 after 13 years of marriage, have remained dedicated co-parents.

The birthday tribute included a rare photo of Bear playing with his father, highlighting the family's continued bond.

"I love my Bear so much. I’m so proud of who he is… and I’m the luckiest mama," Silverstone concluded. The post quickly garnered thousands of likes and warm wishes from fans and fellow celebrities, all celebrating the "grown-up" version of the boy they had watched grow up in the spotlight.
