Gwen Stefani only confirmed her third pregnancy - and that she's expecting a baby boy - when she joined Instagram recently.
But the stars were out in force to celebrate at her baby shower this weekend, with the likes of Kate Beckinsale, Gwyneth Paltrow, Jessica Alba and Chelsea Handler on the guest list.
Gwen, of course, was looking immaculate in a printed long-sleeved top, a black waistcoat, and black skinny trousers. Her hair was flawless in loose waves, and she sported her signature red lippie.
Gwyneth arrived at the Hotel Bel-Air for the bash looking chic and stylish in a black blazer and white loose pants, and mesh ankle boots.
Kate Beckinsale was working spring chic already in a mint blazer paired with geometric-print loose trousers, and finished with glamorous silver stilettos (and, of course, those tumbling curls).
And Jessica Alba, meanwhile, ramped up the style stakes in an animal-print miniskirt, teamed with a simple black jumper, an edgy spiked silver necklace, tights, and super-cool studded peep-toe ankle boots.
e're crushing on Jess' chic, but all ladies looked on top form for the bash, which saw Gwen receive all sorts of gifts.
According to E Online, Jessica Alba bought a "huge diaper cake made up of Honest skull diapers" and a "dinosaur storage bin full of toys, books and clothes," which she picked up at Bel Bambini on her way there.
The source added: "Other guests brought baby clothes from Chanel and Bonpoin. There were tons of gifts that were all wheeled out on a luggage cart and put in Gwen's car."
The shower was decorated with white roses, and boasted a blue and white-themed sweets trolley, which Gwen proudly Instagrammed a pic of, writing: "Baby shower!!! #can't believe im pregs thanku Shelli Azoff for a beautiful #girlyday =blessed."
