Robin Thicke Shares Sweet Photo Of Son Meeting Newborn Daughter

Robin Thicke is one proud father.

On Monday, March 26, 2018, the "Blurred Lines" singer took to Instagram to share a sweet snapshot of his son, Julian, meeting his newborn sister, Mia.

"Lucky Daddy!" Thicke captioned a precious photo documenting the moment his son officially became a big brother. In the pic, both dad and son lovingly gaze upon the newest addition to their family.

Over the weekend, the pop star's girlfriend, April Love Geary, introduced the couple's little girl to the world, sharing the first image showing her face. "My little love," the new mom wrote, captioning a photo of herself cradling her little bundle of joy while sporting a pink hoodie, which read, "Baby girl."

As Nicki Swift previously reported, the pair welcomed their first child together on Feb. 22, 2018. A couple days later, Thicke, who shares 7-year-old Julian with ex-wife Paula Patton, announced the happy news on Instagram. Sharing a video of himself holding his baby girl at the hospital, he wrote, "On 2/22 at 13:33 Mia Love Thicke was born. Thank you God and April Love ❤️!"

Thicke, 40, and Geary, 23, began dating in 2015, and first revealed that they were expecting last August. "Robin and I are very excited to share with you all that we're having a baby!" Geary gushed on Instagram, adding in reference to Thicke's late father, actor Alan Thicke, "The [expected] due date is March 1st, Alan's birthday."

In late January of this year, the pair celebrated an extravagant baby shower in Malibu. "We were so lucky to be surrounded by so much love and joy," Thicke told People, before explaining that they decided on their daughter's name with some help from his son. "Julian came up with the name. And I suggested the middle name Love after her mommy."
