According to WWD.com, Marc Jacobs is engaged to be married to Lorenzo Martone after dating for about a year. The couple plan to go public with the news tomorrow when they arrive in Martone’s homeland of Brazil wearing rings.

Marc has been through so many boyfriends over the years.

Congrats if it’s true!

Christina Ricci (29) has only been dating Owen Benjamin since November, but the couple are now engaged to be married. The couple are also starring in a movie called All’s Faire in Love. We wonder if this is a publicity stunt like when Vince Vaughn and Jennifer Aniston pretended to be dating when they were promoting The Break-Up.

They make such an odd couple. He’s 6 feet 6 inches tall, and she’s 5 feet one inch tall.

Ken Weber confirmed on today that his daughter, realtor Kyla Weber (29), is engaged to marry Vince Vaughn (38).

Vince proposed on Valentine’s Day with a $125,000, four carat, diamond ring. His fiance is from Canada. Vince’s mother was also a realtor from Canada. Vince’s only comment on Weber was last year when he told USA Today:

"I don’t talk much about private matters, but I am in a very happy, serious, committed relationship."

I hope the age difference isn’t too much. Vince seems like a nice guy who deserves to be happy, as does his bride to be. He’s marrying youth, and she’s marrying money. It’s a match made in heaven.

The picture above was taken when the couple were in Cabo San Lucas in February.

Congrats!

Rachel Bilson was overhead saying she and Hayden Christensen are engaged to be married. A source spotted Bilson on a Virgin America flight from LA to JFK Monday night with her mom. The source said:

"A man sitting in front of her on the plane saw a ring on her finger and asked if she was married," the insider said, who overheard Bilson reply, "I’m not married yet, just engaged. I know I look like I’m 15, but I’m actually 27."

Congrats! We wish these two all the luck they’ll need to stay together as a Hollywood couple.

Mandy Moore (24) and Ryan Adams (34), are now engaged. The couple broke up last summer, but now they are back on.

We doubt this engagement, or even a marriage, will last very long. Neither of them seem very mature.
