Christina Aguilera's daughter, Summer Rain, is getting so big! The singer took to Instagram on Aug. 16 to wish her gorgeous little girl a happy birthday. Christina, who also shared a cute home video of her kids [2] in July, posted a photo of Summer sitting next to a giant pink balloon in an apple-print dress, with the caption, "Happy 1st Birthday! My Sweet, Summer Rain." Summer's dad, Matthew Rutler, who popped the question to Christina in February 2014 [3], also gave his daughter a sweet shout-out via Twitter. "You light up life. Happy First Birthday, Summer," he wrote, alongside a precious photo of them cuddling in the sunshine.
The night before their daughter's big day, Christina and Matt attended the Apollo in the Hamptons event, where the singer got a little romantic for her man in front of the A-list crowd [4]. Christina dedicated Etta James's "At Last" to her fiancé before belting out the classic tune for guests including Jack Nicholson, Jimmy Fallon, and Mary-Kate Olsen. See the couple's sweet dedications to Summer above and below, then check out Christina's recent topless Instagram selfie [5].
