Mireille Enos has given birth to a baby boy.
The 38-year-old actress and her husband Alan Ruck welcomed their second child into the world yesterday (23.07.14) and have named him Larkin Zouey Ruck.
A representative for the couple told E! News: "Mireille Enos, Alan Ruck and their daughter Vesper are overjoyed to announce the arrival of their son and brother, Larkin Zouey Ruck. He was born at 7:07am in Los Angeles. He weighs 7lbs 3oz."
The 'World War Z' star and her beau - who announced they were expecting their second child in February - admit they are besotted with their new bundle of joy and believe his arrival was a "miracle".
They told PEOPLE.com: "We are awestruck by the arrival of our little boy. The whole thing is a miracle."
The couple, who got married in 2008, already have three-year-old daughter Vesper together, and the youngster previously admitted she couldn't wait to meet her new baby brother.
She said in February: "I'm excited to meet MY baby."
Meanwhile, Alan, 58, also has daughter Emma and son Sam with his ex-wife Claudia Stefany.

Calvin Harris is reportedly trying to "avoid" Rita Ora.
The 30-year-old DJ - who split from the 'RIP' hitmaker earlier this year - is worried about bumping into the 23-year-old singer this weekend in Las Vegas and is doing everything he can to stay away from her.
A source told the Daily Star newspaper: "Calvin has been asking mutual friends to keep him in the loop of her plans so they avoid each other. He's been doing everything he can to avoid bumping into her.
"Calvin is in Vegas almost every week and feels like it's his turf. He doesn't want the pressure of worrying about seeing her."
However, friends believe the 'Summer' hitmaker is more concerned about seeing his former flame with her new boyfriend Ricky Hil, the son of Tommy Hilfiger, whom she has been dating since the beginning of the month.
The insider explained: "If Calvin bumps into Rita and she's with her new boyfriend, he'll be gutted. He wants to know which parties and events Rita is planning on going to so he can stay well clear. Calvin knows that if they accidentally end up in the same place, it'll be beyond awkward for the both of them."
Calvin announced on Twitter in June that he'd ended his year-long relationship with Rita "some time ago", but wished her all the best in the future.
Rita then took to her account a week later to claim she had "moved on" from her former lover.
She tweeted at the time: "I don't usually address speculation but I've had an incredible time with Calvin, and I will treasure the memories.
"I've moved on so I hope people will respect that and do the same."

Eva Mendes' pregnancy was reportedly "unplanned".
The 40-year-old actress is expecting her first child with boyfriend Ryan Gosling, 33, but the baby news allegedly came as a complete shock to the couple.
A source told RadarOnline.com: "It [the baby] was completely unplanned.
"Ryan was surprised, especially because they had broken up early last year, only to get back together."
The 'Hitch' star moved into Ryan's modest home in Studio City, Los Angeles, but the property is fairly small and the pair are reportedly looking for a bigger house ready for when their new bundle of joy arrives.
The source explained: "The house is quite small, and only has two bedrooms. Eva has been looking for a bigger house to live in with Ryan once the baby is born."
Meanwhile, the pair, who have been dating since 2011, managed to keep the pregnancy a secret until recently by only telling a few close friends and family members.
An insider said previously: "[Eva] just hasn't ever wanted anyone beyond her close friends and family knowing more than they had to. And Ryan is certainly private and always has been."
The brunette beauty, who is due to give birth in October, "barely left the house" after she found out she is pregnant in a bid to keep the news underwraps.
The source added: "Their lives completely changed as soon as Eva got pregnant. They used to travel all over the place together and go on hikes with their dogs.
"Ryan has been taking care of her, picking up food and running errands. He has been very supportive about keeping things a secret."

Nicola Roberts has split from her boyfriend.
The former Girls Aloud singer reportedly called time on her six-year relationship with businessman Charlie Fennell late last year after their romance fizzled out.
A source told the Daily Mirror newspaper: "Nicola and Charlie split at the tail end of last year. They just kind of grew apart - they had a great run but they both felt their relationship had come to an end."
The 28-year-old beauty - who had pet pooches Ronnie and Reggie with Charlie - is enjoying the single life and doesn't feel ready to settle down just yet.
The source explained: "Nicola is really enjoying being single again. She's been back out partying loads and is really enjoying making new friends and being out at showbiz parties. She's definitely still single, and she's not looking to settle down quite so much so soon."
Nicola - who previously said she wants "masses" of children - insisted earlier this year that she's not looking to start a family any time soon, but hopes to eventually.
She said: "It's in my future but not in my near future."
Meanwhile, Nicola's ex-bandmate Cheryl Cole married her beau Jean-Bernard Fernandez-Versini earlier this month following a whirlwind three-month romance.
The other Girls Aloud members are also getting ready to settle down as Kimberley Walsh is expecting her first child with long-term boyfriend Justin Scott, Nadine Coyle gave birth to her daughter Anaiya in February and Sarah Harding is happily dating DJ Mark One.

Alyssa Milano knew she was expecting a girl.
The former 'Charmed' star had a feeling she was carrying a baby daughter, even before it had been confirmed by a doctor, because she suffered with morning sickness, which she didn't experience when she was pregnant with her son Milo three years ago.
Speaking in the August/September issue of Fit Pregnancy magazine, she said: "I had morning sickness this time, but it went away right at 12 weeks. With Milo, I didn't have a minute of morning sickness. So I knew it was going to be a girl."
The 41-year-old actress - who gained 55lbs in her first pregnancy - is due to welcome the tiny tot into the world in early autumn and she insists she's not bothered about piling on the pounds while carrying her second child.
She explained: "A female body is not made to look good in a bikini. It's made to give birth and have a baby and be a cosy companion for it afterward. And for my body, that meant putting on a lot of weight.
"I didn't indulge in fast food or junk food, so I knew it was a healthy weight. I just realised: This is what my body needs to do to have a healthy baby."
Meanwhile, Alyssa - who announced her pregnancy in March - is glad she waited until she was older to start making a family with husband David Bugliari.
She said: "I loved waiting a long time to be a mom. I'd had my ladies' lunches and my shopping days."

Naya Rivera has adopted her husband's surname on her social media accounts.
The 'Glee' star only tied the knot with Ryan Dorsey last weekend, but she couldn't wait to flaunt her new marriage as she has already changed her Twitter and Instagram handle to Naya Rivera Dorsey.
The 27-year-old actress' wedding day took place in Cabo San Lucas, Mexico, on July 19 and the couple exchanged their vows in front of friends and family.
They told People magazine earlier today (23.07.14): "We feel truly blessed to be joined as husband and wife. Our special day was fated and everything we could have ever asked for. True love always prevails."
The wedding came as a huge shock to fans as it was only revealed last week that the couple were dating after they were spotted on vacation together in Mexico.
However, the newly-weds have been friends for four years after they met when Ryan moved to Los Angeles.
Meanwhile, the nuptials came just three months after Naya's ex-fiancé Big Sean called off their engagement in April following just six months of dating.
A representative for the rapper said at the time: "After careful thought and much consideration, Sean has made the difficult decision to call the wedding off ... Sean wishes Naya nothing but the best and it is still his hope that they can continue to work through their issues privately."

Ariana Grande's grandfather has died.
The 21-year-old singer has been left heartbroken after her grandpa passed away last night (22.07.14) following an ongoing battle with ill-health.
Taking to her Twitter account today (23.07.14) Ariana broke the devastating news to her fans, tweeting: "Thank you for your continuous love and light over the past few weeks ... we did lose my favourite person to ever exist yesterday, my grandpa.
"If only you all knew how amazing he was ... my heart hurts so much. It's beyond broken but I got to hold his hand and watch him find his peace.
"This is the hardest thing imaginable but I'm so grateful that I got to spend this time with him and my family. Taking care of him & loving him."
The 'Problem' hitmaker's brother Frankie is currently taking part in 'Big Brother US', but she admits her sibling won't be told about their grandfather's death until he has completed his stint on the gameshow.
She tweeted: "asked grandps last week if he wanted us to pull frankie off bb & he said "no way! he's gotta play the game even tho i don't understand it" (sic)."
Meanwhile, the brunette beauty was forced to cancel a trip to London recently after she rushed to her grandpa's bedside when it became apparent his health had deteriorated.

Jennifer Aniston and Sandra Bullock have reportedly become the "best of friends".
The 45-year-old star and the 49-year-old actress have struck up a close relationship after meeting at mutual pal Gwyneth Paltrow's house party and bonding over their previous painful divorces and past boyfriends.
A source told Us Magazine: "Jen and Sandra are new best friends forever. They're very excited about the new friendship."
The former 'Friends' beauty and the 'Gravity' star - who have both dated actor Tate Donovan, 50, in the past - have been spending a lot of time together ever since.
The source explained: "Sandra and Jen have a lot in common and enjoy each other's company. They have been having each other over for dinner regularly."
The new pals were rumoured to be working with each other earlier this year after they were both linked to a comedy movie with Cameron Diaz, but the upcoming plans are yet to be confirmed.
Meanwhile, Jennifer - who was married to Brad Pitt from 2000 until 2005 - is currently engaged to Justin Theroux following their three-year relationship.
While, Sandra, on the other hand, has four-year-old son Louis - whom she adopted with ex-husband Jesse James - but raises him as a single-parent.

Lana Del Rey likes to have a "passionate love".
The 29-year-old singer believes a large proportion of a relationship is based on sex and she admits she isn't interested in romance unless it is "physical".
Speaking in the new issue of Complex magazine, she said: "I like a hands-on love. How can I say this without getting into too much trouble? I like a tangible, passionate love. For me, if it isn't physical, I'm not interested ... Everything else is so hard; hopefully love is the one thing that is actually fun."
Meanwhile, the 'Born to Die' hitmaker recently ended her relationship with musician boyfriend Barrie-James O'Neill, whom she first began dating in 2011, because she wanted to feel "free" again.
She said previously: "We are currently not together. He is a wonderful person. But there are some things with which he has to deal. I will not explain it in detail.
"This was hard on our relationship, I no longer felt free."
However, despite calling time on her romance with Barrie, the brunette beauty admits she hasn't ruled out settling down with someone in the future and having children with them.
When asked if she would like to get married at some point, Lana replied: "I'd love to. And I would like to have children. Hopefully it will work out sometime."
Lana has since sparked rumours she's dating Vogue photographer Francesco Carrozzini after they were spotted looking cosy together in Los Angeles and New York last month.

Jenni 'JWoww' Farley has claimed she "blacked out" when she was giving birth to her daughter.
The former 'Jersey Shore' star - who was induced 39 weeks into her pregnancy - admits her labour was "way more painful" than she expected but she was overcome with emotion when Meilani entered the world on July 13.
Speaking to In Touch magazine, she said: "I blacked out [during my labour]. I thought I was going to die."
However, the brunette beauty managed to put the painful experience behind her when she locked eyes on her daughter's adorable face for the first time.
She explained: "I just cried [when she was born]. She was so beautiful."
The reality TV star's best pal Snooki, who is also expecting a baby girl later this year, has been spoiling the tiny tot "rotten" after being named as her godmother.
Jenni also revealed how much of a support Snooki - who has two-year-old son Lorenzo with her fiancé Jionni LaValle - had been throughout her pregnancy.
The 28-year-old star announced the birth of Meilani - whom she has with her fiancé Roger Matthews - on her Twitter account two days after her arrival.
She tweeted at the time: "Our baby's first breath took ours away...So blessed!!!
"Mommy and daddy haven't slept because we can't stop staring at our baby, Meilani! I don't ever want to put her down to use my phone! Lol (sic)."

Dora Bryan has died aged 91.
The 'Last of the Summer Wine' and 'Absolutely Fabulous' actress passed away with her sons Daniel and William Lawton by her bedside, according to The Brighton Argus newspaper.
Dora, who was based in Brighton, had lived at a nursing home in Hove, south east England, in the final years of her life.
Her son Daniel said: "It was heartbreaking but it was peaceful. She just left us.
"She was a tiny woman but her constitution was incredible.
"She loved being on stage, that's what she wanted. Not only did she do it, but she was good at it.
"She was a star and a mum."
Dora played Ros Utterthwaite in 50 episodes of 'Last of the Summer Wine' between 2000 and 2005 and also had roles in 'Absolutely Fabulous' and the 'Carry On' films.
The actress began her stage career at a young age and during the Second World War, she joined the Entertainments National Service Association (ENSA) to entertain British troops who were stationed in Italy.
Dora was married to cricketer Bill Lawton for 54 years until his death in 2008.

Kanye West is "jealous" of Kim Kardashian's ex Reggie Bush.
The 'Keeping Up with the Kardashians' star - who has 13-month-old daughter North West with Kanye - has reportedly banned her family from mentioning her ex-boyfriend in her husband's presence because the 'New Slaves' rapper is worried the NFL football player still has feelings for Kim.
The topic of Reggie - whom Kim dated for three years from 2007 to 2010 - was raised in the Kardashian-Jenner household in the last fortnight when he married his girlfriend Lilit Avagyan, who bears a striking resemblance to the reality star.
A source told RadarOnline.com: "Kim went out of her way to avoid reading about Reggie's wedding to Lilit last weekend. She doesn't like to discuss Reggie, not even with her sisters. And Kim did remind her family to not mention Reggie's name in front of Kanye, because he is very jealous of him.
"There have been numerous assurances by Kim that Kanye has nothing to be jealous of, but there is always an argument when his name comes up.
"Kanye thinks that Reggie is still in love with Kim because he married a woman that looks exactly like her. And honestly, that isn't lost on Kim either."
Reggie, 29, is good friends with Kim's stepbrother Brody Jenner, who attended the athlete's wedding earlier this month but missed his sibling's nuptials to Kanye, 37, in Florence, Italy, in May.
A source previously hinted Kim and Brody "aren't close", adding: "Of course it's a huge diss to Kim that her stepbrother went to her ex-boyfriend's wedding and not hers!"
