Mariah Carey and Nick Cannon celebrated the impending birth of their twins with a lavish baby shower held over the weekend in Beverly Hills.

The happy couple arrived to the Conservatory Grill at the Montage Hotel in a black Rolls-Royce, given from Cannon to Mimi as a Christmas gift, reports PEOPLE. Guests including Randy Jackson dined at cocktail tables decorated with pink roses and blue hydrangeas, colors representing the genders of their expected boy and girl babies.

After the evening event, the mom-to-be posted a blog thanking all of her guests for attending. “Thank you SO much to all who came to the baby shower last night and all who couldn’t be there but sent such beautiful presents and sweet messages!” wrote the dashing diva, who was presented with an “Always Be My Babies” Lamb book from her fans.

“FYI-we so had a ‘moment’ in the middle of the shower when they presented the book to me and everyone thought it was the cutest, most thoughtful thing ever! Clearly, only the Lambs would swing something like that home!!!” she continued. “It was the best moment of the night. I can’t wait for the twins to read the messages and feel the love!!!”
