Uh, because you officially separated a month ago!
The insider added that Jon presented Hailey with a $180,000 engagement ring designed by Edouard Nahum during a romantic getaway to St. Tropez last Sunday.
Jon, you have eight kids and no visible means of support. Dial back on the bling, dude.
"They started dating two months ago and they both just knew the other was the one instantly," said the anonymous source, speaking in the tabloidy Cupidy tongue of so many previous anonymous sources.
While Jon's kids - did we mention he had EIGHT - were not with dad on the Riviera, Jon and Hailey met with Ed Hardy clothing designer Christian Audigier, who must be planning a new deadbeat-dad line.
Jon and Hailey Plus Zero stayed in a $2,000-a-night room at the Chateau de la Messardiere, drank champagne, ate lobster, sailed on Audigier's yacht and shopped in Antibes.
Not having to fret about a babysitter, at night they went to St. Tropez's V.I.P. Room nightclub.
"Hailey was flashing her ring around and they were kissing and hugging," said another anonymous source.
"I think she's with him to use his money. No doubt in my mind," said an unnamed college "friend" of Hailey.
"Hailey is fame-hungry," the college "friend" says. "She auditioned for 'The Real World.' I'm not surprised she's with someone in the public eye."
Aw, thanks for the shout-out.

Pennsylvania father of eight meet a 22-year-old NYC party girl?
Us Weekly says Hailey is the daughter of the plastic surgeon who performed Kate's free post-sextuplets tummy tuck in 2006.
