Kate Winslet's son is named in honour of the fire she escaped in 2011.
The 'Divergent' actress met her now-husband Ned Rocknroll when they fled a fire on his uncle Sir Richard Branson's Necker Island two years ago, so their little boy Bear Blaze was given a middle name to remind them of the incident.
Kate said: "Bear's second name is Blaze because my husband and I met in a house fire basically. Well, we did!
"The house burned down and we survived. But we wanted something of the fire and so Blaze was the name that we came up with."
Kate - who also has children Mia, 13, and Joe, 10, from previous relationships - chose three-month-old Bear's name early in her pregnancy and he is named after one of her old friends.
She explained to talk show host Ellen DeGeneres: "When I was pregnant with Mia and Joe, I didn't name them before they came out because I always felt like I just have to see them and see who they're going to be.
"But of course, this time around there's Mia and Joe and the whole pregnancy is about 'what are we gonna call the baby?' So it was really lovely, actually. They were very much included and we settled on Bear quite early on.
"A friend of mine when I was younger was nicknamed Bear and I just had always really loved it. And he was very much a bear. He was everyone's shoulder to cry on. He was a big bear hug, he was a great figure in my life, and I just had always remembered him and so that's where it came from."
The 'Labor Day' actress was also asked why her new baby didn't take the surname of his father, who was born Abel Smith but changed his name several years ago.
She smiled and said: "Why do you think, Ellen?"

L'Wren Scott's social media profiles have been taken down.
The late 49-year-old fashion designer's accounts on twitter, Facebook and Instagram have been removed following outrage when the pages continued to update after she was found hanged in an apparent suicide at her New York apartment yesterday (17.03.14).
Scheduled messages, including a picture of a tree, posted to her accounts an hour after L'Wren's assistant found body, prompting her social media team to be branded "insensitive" and "disrespectful" for not blocking the updates.
It has been claimed that L'Wren - the long-term partner of Rolling Stones frontman Mick Jagger - was almost $6 million in debt when she died.
According to accounts for her business, LS Fashion LTD, which were filed in the UK in October 2013, the company was in trouble, with a deficit of $5,899,000 and the designer owing creditors $7,641,000.
Friends had also been worried about the former model - who reportedly refused offers of financial help from Mick - in recent weeks, as she had been "acting strangely" and not answering phone calls.
One source said: "They've known that something was going on, and it's been going on for at least a week."

Melissa George was in labour for three days with son Raphaël.
The 'Good Wife' actress and her boyfriend Jean-David Blanc welcomed their son into the world on February 6, and although she was having contractions "every five to eight minutes" for 72 hours, she insists she had a "great time" waiting for the new arrival.
She told HELLO! magazine: "I was in labour for three days, around the clock, with contractions every five to eight minutes.
"I had a great time walking up and down the halls and going from the bath to the shower, to the balloon balls. I had the bar by the head to hold on to so I could squat and let gravity do its work."
Although Melissa was in hospital for eight days, she enjoyed the experience since she shared it with a friend who was going through the same thing.
She added: "We had a great time because a very good friend went into labour two days after me. She was next door to me so all our friends in Paris could visit both of us."

Mel C has got a new feather tattoo.
The former Spice Girls star has had the design etched onto her right arm and it is joined to her famous barbed wire inking, which wraps around her entire upper arm.
Mel - full name Melanie Chisholm - proudly showed off her latest tattoo in a photo she posted on her Instagram account on Tuesday morning (18.03.14).
The pop star sported a make-up free face and scraped her hair up into a high ponytail as she posed with her arm above her head to reveal the design along with the caption, "New Ink."
Mel's decision to get the tattoo comes after the 'Wannabe' singer's admission she had toyed with the idea of getting her barbed wire tattoo removed, because the design - which was popular in the 90s - had become outdated.
Mel told BANG Showbiz: "Sometimes I think, 'I hate that one, I wish I could get rid of it.' The first one I ever got was the band around my arm, it's just so very 90s, it just looks really dated."
The 40-year-old star even considered undergoing painful laser tattoo removal surgery to get rid of the design, but couldn't go through with the procedure because she has become so attached to it.
She explained: "When I saw myself photographed and they were airbrushed out, it just looked so odd, they're very much a part of me so I've grown to love them again.
"I'm a bit indecisive. The laser treatment is painful and expensive; you may as well just leave it."
