Sara Gilbert is engaged to rock musician Linda Perry — a surprise development she described in full today on The Talk.

Listen in as she explains how Perry, 47, proposed marriage in a park with musicians … and special T-shirts.

In 2011, Gilbert, 38, addressed her split from TV producer Allison Adler on The Talk. The two share custody of son, Levi, 8, and daughter, Sawyer, 5.

Perry is the former lead singer of 4 Non-Blondes and has produced several hit songs for Pink, Gwen Stefani and Christina Aguilera.
