Just a day after the video-making duo took J.Lo's twins to see the Easter Bunny and later hit the town, the lovebirds rang in Smart's big 2-5 together Friday, kicking off the fete with an intimate dinner at upscale Italian hot spot Cecconi's in West Hollywood.
"@BEAUcasperSMART 'Beau has a birthday we're so glad we hope its the happiest Birthday Beau ever has!' HAPPY BIRTHDAY BEAR!!!," Lopez tweeted.
And why wouldn't it be happy? A source confirms to E! News that J.Lo really splurged for the birthday boy.
"Yes, she did buy him a white pickup," said the source. "He really wanted one and she surprised him. He had no idea he was getting it."
The 42-year-old American Idol judge, who rented out the restaurant's Butterfly room for the evening to accompany 25 of Smart's family and friends, headed to Cecconi's wearing a turquoise, tight-fitting Michael Kors dress, while Smart opted for a casual black jacket and cap.
Earlier in the day, Lopez and Smart were spotted shopping together in Beverly Hills.
Happy birthday indeed!
