The quirky blonde fashionista's sister took to Twitter to congratulate the happy couple moments after news of the marriage made headlines.
"Seen as my fams business is splashed all over the press dis mornin pffffffttt," she tweeted followed by a picture of the newlyweds via Instagram. The caption of the picture read "Cat's out of the bag! Congratulations to my sister and mi sic new bro in law Giovanni. Freakin love them so much!"
Skipping the ring bearers and flower girls (and sticking to Deyn's signature iconoclastic style), the duo chose a low-key celebration at the Los Angeles County Registrar.
These two are quite the sneaky lovebirds!
