Kourtney Kardashian received a sweet and musical birthday present with help from son Rocky Thirteen Barker.
The Lemme founder's husband Travis Barker shared a video of his wife being serenaded by a female singer performing the classic Temptations song "My Girl" on a decorated deck while the couple’s 17-month-old son sat beside his mom on a daybed and strummed and tapped on a ukulele.
"46 years young my beautiful wife," the Blink-182 drummer captioned the clip, which he posted to his Instagram Stories April 18. "Happy birthday @kourtneykardash."
Travis later shared more photos of Kourtney and their son, including a sweet pic of the two on a private jet, where his wife was reading notes on an apparent renovation project on one of their homes.
"I love you and I’m so thankful for you my beautiful wife," the rocker wrote on his Instagram. "Couldn't ask for a better Mom or better life partner. Can’t wait for 46 more years with you."
And Rocky appears to be following in his dad's musical footsteps. On April 14, Travis gave fans a glimpse at Rocky playing on a small drum on a luxury ensemble sofa. Earlier this month, Kourtney posted a pic of the couple's youngest son touching the keys of a Yamaha grand piano on a family trip to Disneyland.
Kourtney—who also shares kids Mason Disick, 15, Penelope Disick, 12, and Reign Disick, 10, with ex Scott Disick—received a slew birthday well-wishes from her loved ones, including members of her and Travis' blended family.
"Happy Birthday! I just want to take a moment to let you know how much you mean to me," wrote Travis' daughter Alabama Barker. "You've shown me love, patience, and support in ways that I'll always be grateful for. Thank you for being such a kind, strong, and beautiful presence in my life."
The 19-year-old continued, "You've made a bigger difference than you probably realize, and today I hope you feel just how loved and appreciated you truly are. Wishing you a year full of joy, peace, and everything your heart desires. I love you so much @kourtneykardash."
Kourtney responded, "This made me cry. I love you so much."
Travis' stepdaughter Atiana De La Hoya, 26, also paid tribute to the Poosh founder on her birthday.
"@kourtneykardash !! Happy Birthday to the most beautiful kind generous soul," she wrote, "you are such a light to everyone who knows you and such a blessing to my life, to many more memories love you !!"
Kourtney responded, "I love you more."
