Katherine Heigl is relying on technology to give up smoking – she’s using an electronic cigarette to calm her cravings.

The “Knocked Up” star, 31, has battled with her addiction to tobacco since she was 24 years old, but vowed to quit last year after admitting she had become “a slave” to her habit.

Heigl was also pushed to stop smoking after becoming a mother to adopted daughter Naleigh in September.

But she hasn’t completely snubbed her dependency on nicotine – she was snapped puffing on an electronic cigarette on the set of her new film “One For The Money.”

The device provides inhaled doses of nicotine through a vaporized solution so users don’t have to breathe in harmful smoke.

Katherine Heigl is sad to be finally leaving “Grey’s Anatomy” because her fellow cast members became like “family” during her six-year stint on the hit show.

Heigl has been dogged by rumors of a departure from the show ever since she landed her movie breakout role in 2007′s “Knocked Up.”

After taking a three-month hiatus from the hit medical drama, Heigl finally announced in March that she will no longer be a part of the series because she wants to focus on being a mom to adopted daughter Naleigh.

Katherine Heigl has suffered a real yet embarrassing wardrobe malfunction.

While accepting the ShoWest award for Female Star of the Year in Las Vegas Thursday, one of the straps on her red Donna Karan dress broke. Shocked, the actress, 31, struggled to continue with her acceptance speech.

Access Hollywood host Billy Bush immediately ran to her rescue, holding her strap in place.

“Oh my,” he Twittered. “Hosting showest awards in LV. Heigl comes up to get award, dress strap breaks…I hold her top on while she accepts!”

Katherine Heigl showed what it takes to be a celebrity with a heart – the Knocked Up star saved the lives of 25 Chihuahuas, who were about to be “euthanized”.

Heigl and her mother’s Jason Debus Heigl Foundation donated 25,000 dollars that the stray pooches could be flown from LA to their new families in Boston, Massachusetts.

The dogs will now be available for adoption at the Humane Society for Greater Nashua and Salem Animal Rescue League of New Hampshire.

“All 25 would have been euthanized if we didn’t take them. We’re just so happy to be saving their lives,” Contactmusic quoted Humane Society director Karen Bill, as telling People mag.

Katherine Heigl and husband Josh Kelley have completed their adoption of a baby girl from Korea.

Heigl spokeswoman Melissa Kates says the couple named the 10-month-old Nancy Leigh, after the actress’s mother Nancy and her sister Margaret Leigh. The girl will go by the nickname Naleigh.

Katherine Heigl and Gerard Butler were left fearing for their lives after a bomb scare at a Los Angeles hotel on Saturday.

The Hollywood stars were inside the Four Seasons Hotel to promote their upcoming film, “The Ugly Truth,” when they were forced to evacuate, along with 400 other guests.

Heigl and Butler were left waiting outside the luxury complex while police investigated the premises after a phone call warned of a nearby bomb, according to People.com.

The Scottish actor was seen posing for pictures with members of the AC Milan soccer team, who were in the city to play a game against Los Angeles Galaxy on Sunday night.

Cops found no unattended packages or luggage and the hotel reopened two hours later.

Katherine Heigl is set to star in Life as We Know It, a film about two singletons who must come together to raise an orphaned child, her rep confirms to E! News.

Katherine Heigl’s rep lashed out at a report in the  New York Post that said the actress was dropped from an upcoming A-list movie ensemble due to her asking price of $3 million for 14 days of work. The “Grey’s Anatomy” star, who broke into movies with the 2007 comedy “Knocked Up,” was expected to join Hollywood superstars Julia Roberts,  Jennifer Garner  and  Anne Hathaway  in the romantic comedy “Valentine’s Day,” due to hit screens in 2011. The rep told PageSix, “The story is ludicrous. Early negotiations are a daily occurrence in this business, and just for clarification, Katherine walked away from this project for multiple reasons.” About 3 million of them?

Katherine Heigl, who plays Dr. Izzie Stevens on ABC’s hit medical drama Grey’s Anatomy, says she’s sticking with the series that made her a star — unless producers have other plans.

“I don’t know if I live or die. I don’t know how Izzie fares,” the actress, 30, told the Associated Press at a studio party on March 27 to mark the show’s 100th episode. On Thursday’s episode, Izzie was seen surviving brain surgery.

Calling the set “one of my favorite places to be,” Heigl said “I’m there” if Izzie remains part of Grey’s Anatomy.
