Angelina Engaged from Jersey Shore

We've got a situation. Bad girl Angelina Pivarnick was completely caught off-guard at New York Fashion Week on Wednesday when her boyfriend, David Kovacs, randomly got down on one knee and popped the question, reports RadarOnline.

The reality-star-turned-singer was completely surprised when David turned to her and proposed as they walked the red carpet at the Style360 Sachika’s Fashion Show. "Oh my God, the kid just got down on one knee and I was like, what the f**k?" Angelina tells Radar.

Several people saw the very public proposal. One insider confirmed, "The ring is platinum and 2.5 carats." Angelina was supposedly completely shocked, said onlookers, and "covered her face with her hand to hide her excitement." (Or embarrassment?) "She kept dropping the ring on the carpet because she was so nervous. But David picked her up and the two hugged and kissed," an onlooker tells Radar.

The reality star, who left Jersey Shore during the season taped in Miami due to multiple feuds with her housemates, has since gone on to start a singing career. She's also scheduled to appear in an upcoming film, "Every Time I Go to Staten Island Something Bad Happens." Check out more photos of Angelina's surprise engagement here.

Kat Von D's Engagement Ring Details

They may not be saying much about their engagement, but Kat Von D isn't afraid to flash her new diamond engagement ring. And what a ring it is!

That tattoo artist, who announced her engagement to Jesse James on Thursday, is reportedly wearing a 4-carat sparkler designer by Neil Lane, reports Us magazine. The ring includes a four-carat center stone, plus other smaller stones around the edge in a delicate filigree pattern with scroll work. The ring is from Neil Lane's archival collection. Other sources are speculating that it's the same ring that Kat has been wearing on her ring finger for about the past four months, even though they only recently announced their engagement.

At the 16th Annual Los Angeles Art Show Opening Night Premiere Thursday night, Kat stayed tight-lipped about the engagement, but was willing to gush about her Jesse. "I feel really lucky," she told Us magazine. "I think in the past I thought I knew what love was. I think I am growing up a lot too and realizing the truth in a lot of things and feel really blessed now."

Jesse James and Kat Von D Engaged

It's a tattoo match made in heaven! Motorcycle king, Jesse James, has announced his engagement to tattoo guru Kat Von D, reports People.com.

Says Jesse, "You know sometimes the public and press gets it wrong. This is one of those times. 2010 was actually the best year of my life because I fell in love with my best friend. An amazing woman who stood behind me when the world turned their backs." Jesse James got divorced from actress Sandra Bullock last year after he was caught having an affair with another tattooed mistress. His divorce from Sandra was finalized last June, and Jesse and Kat Von D apparently have been dating since the summer.

"I have never met anyone so kind and loving and committed to making the world a better place every day. My love for her is beyond description... Growing old with her is going to be a f****n' blast!" Jesse, 41, tells People. Likewise, Kat, 28, seems to be totally smitten with her new fiance. "There is no one else for me. He's the one," the LA Ink star says to People.

No word yet on when the wedding will be (but we're no-so-secretly hoping matching tattoos and motorcycles are somehow involved).
