I'm sure all the guys know more than enough about Australian supermodel Miranda Kerr. And now the hottie has announced her engagement to Snapchat founder and CEO, Evan Spiegel on her Instagram account. Although the announcement is way too cute, I wonder if all is well between the couple considering Spiegel's Snapchat is a business rival to Instagram! And he had also rejected a $3 billion, all-cash acquisition offer from Mark Zuckerberg’s company in 2013!
