When Snapchat CEO proposes, you put it on Instagram

Miranda Kerr said yes.

The 33-year-old model is engaged to marry Snapchat co-founder and CEO Evan Spiegel.

She made the announcement on her Instagram account - using a Snapchat filter - on Wednesday, with a photo of a diamond ring and the caption "I said yes!!!"

This will be the second marriage for Kerr, who was previously married to actor Orlando Bloom. They have a 5-year-old son together. Spiegel, 26, has never been married.

He co-created Snapchat when he was a student at Stanford University.
