Clearly happy, the former Victoria Secret model shared news of her engagement on her Instagram account right after Spiegel popped the question in the early hours of Thursday morning local time (AEST).

The photo had Kerr showing off her diamond ring alongside with animations of Spiegel bending down on a knee with the words "marry me" appearing on the photo.

"I said Yes!!!" Kerr said in the photo's caption.

Spiegel, 26, is one of the world's youngest self-made billionaire and is estimated to be worth about?$2.1 billion.

This is the second marriage for Kerr and the first for Spiegel. Kerr was formerly married to Hollywood actor Orlando Bloom, with whom she has a son.
