While we were busy hatching a sartorial plan of attack for Cyber Monday, Lindsay Lohan's boyfriend of two years Bader Shammas was planning something of his own—a proposal. On Sunday, the Mean Girls

actress took to Instagram to announce the result of such plan with her 9.8 million followers, sharing four images of the couple, as well as a third addition to their family: a massive diamond ring from Harry Winston. (Nice.) "My love. My life. My family. My future," she captioned the slideshow. 

According to WP Diamonds's CEO Andrew Brown, Lohan's new rock "appears to be a [three carat] cushion or radiant solitaire, set in a simple yellow gold setting." Though timeless in design, her ring style is actually one of this year's top engagement ring trends, with cushion-cut styles growing increasingly popular among celebrities like Lily Collins, who got married in September. Next in line: Lindsay Lohan.
