Kim Kardashian and Kanye West looked like the happiest couple in the world on Monday as they were spotted together for the first time since their baby news.
The parents-to-be were spotted at Los Angeles International Airport with their arms wrapped around each other while exchanging affectionate glances.
Pregnant Kim's mother and manager Kris Jenner - not one to miss out on a media opportunity - followed closely behind.
Kim is expected to be joined by Kayne tonight as she hosts a New Year's Eve party in Las Vegas - for which she is said to be earning a staggering $300,000.

The reality star - who is around three months pregnant and due at the end of June - won't take a break as the curvy brunette will ring in the new year at 1 Oak on the Vegas strip, a gig that has been heavily promoted by the Mirage Hotel.
Tickets are $125 for women and $150 for men, while it's $3000 to hire a table. And that is without the cost of any alcohol.
Earlier on Monday Kim opened up for the first time about being pregnant - but admitted the happy news is tinged with sadness.
The 32-year-old TV personality said she and boyfriend Kanye West feel 'blessed' but wished that her late father Robert and his late mother Donda were still around to share in their joy.
Taking to her blog on Monday, Kim wrote a message titled 'New Year, New Beginnings'.
She wrote: It’s true!! Kanye and I are expecting a baby. We feel so blessed and lucky and wish that in addition to both of our families, his mom and my dad could be here to celebrate this special time with us.
'Looking forward to great new beginnings in 2013 and to starting a family. Happy New Year!!! Xo
Kim's father, powerhouse attorney Robert Kardashian, died in 2003, aged 59, just weeks before Kim's 23rd birthday, after losing his battle to esophageal cancer.
In 2007 Kanye's mother Donda died aged 58 due to complication from cosmetic surgery.
Kim and Kanye, 35, have admitted in the past that their mutual loss of a parent has been something they have formed a close bond over as their friendship blossomed into romance.
The couple's baby news was first revealed by Kanye onstage during his concert in Atlantic City on Sunday night as Kim watched from the audience.
The rapper said 'stop the music', then announced 'make noise for my baby mama right here,' with a wide smile. Kanye's announcement prompted a flurry of excited tweets from the audience.
Kim, who was sat in the audience during the show, is said to have not known that her man would reveal their pregnancy and was in shock like many of the rappers fans.
Her spokesman confirmed shortly afterwards that the pregnancy buzz was indeed true.
The two have been dating for eight months. They have previously denied pregnancy rumours.
Kim is thought to be around the 12-week mark.
Kim and Kanye were last seen together on Christmas Day when they attended a basketball game to watch Kim's brother-in-law Lamar Odom play with his new team The Clippers.
Kanye was seen carefully attending to his girlfriend and holding her hand as they sat side by side in the front row. They left at half time, with Kim later tweeting that she felt 'unwell'.
'In bed with the flu all day. Praying this goes away fast!' the Keeping Up With The Kardashians star wrote.
Kim won't be letting her pregnancy get in the way of her work - she is hosting a party in Las Vegas for New Year's Eve at the 1 Oak nightclub.
Kim will earn a six-figure sum for the appearance with tickets costing $125 for entry into the VIP area and $3,000 for a table, according to TMZ.
Of course, Kim is still married to her estranged second husband Kris Humphries. The pair's divorce has been prolonged as the basketball star has insisted on a court case, claiming the marriage should be annulled as it was 'fraud'.
After the news of Kim's pregnancy broke late on Sunday her excited family took to Twitter.
Sister Kourtney wrote: 'Been wanting to shout from the rooftops with joy and now I can! Another angel to welcome to our family. Overwhelmed with excitement!'
And little sister Kendall added: 'Whos excited about the KIMYE babbyyy?! :D weeee'.
Khloe wrote: 'KIMYE!!!!! Keeping secrets is hard with so many family members! 'Especially when you are so freaking excited!!!!! LOVE is everything!!!!
Khloe‘s husband Lamar tweeted: 'I’m excited for Kanye and my sister! There’s nothing like bringing life into this world!
'Let’s keep Gods blessings coming!'
And Grandma-to-be Kris Jenner added: 'I'm a happy girl !!!!!!!!! Wowza!'
Kanye spent the Christmas period with Kim's family, who have welcomed him with open arms.
Kim has also become close to Kanye's family after being he took her to visit them in Oklahoma City while visiting his mother Donda West's grave last month.
Since Kim and Kanye began dating in April they have rarely been apart.
Despite the shortness of their relationship, the two have been friends for years.
It has even been speculated that the rapper had been in love with Kim back in 2009, when he appeared to refer to her in his track Knock You Down.
At the time the song was penned, Kim was in a relationship with NFL star Reggie Bush, whom she went on to date on and off for three years.
The song includes the lines: 'You was always the cheerleader of my dreams... To seem to only date the head of football teams... And I was the class clown that always kept you laughing... We were never meant to be, baby we just happened.'
He then goes on to rap: 'You should leave your boyfriend now.'
And in December 2010, Kanye was on hand when Kim filmed her music video Jam (Turn It Up).
In scenes later broadcast on her reality show Kris Jenner was seen jokingly criticising Kanye for eyeing up Kim, telling him: ‘Don’t be looking at her a**’.
Not one to miss a beat, quick-witted Kanye replied: ‘I’ve never seen it actually.’
