Happy Birthday, Summer! Christina Aguilera Celebrates Daughter’s First Birthday

Sweet Summer time!

In honor of their daughter’s first birthday, proud parents Christina Aguilera and her fiancé Matt Rutler took to Instagram on Sunday to celebrate Summer Rain‘s major milestone.

“Happy 1st birthday! My sweet, Summer Rain,” Aguilera, 34, captioned a cute photo of her second child pointing toward the camera.

Rutler posted his own picture, sharing a candid of the father-daughter duo snuggling in the sunlight while standing in a blooming flower garden.

“You light up life. Happy First Birthday, Summer,” Rutler, a film producer, wrote.

The first-time father has shared several snapshots of his baby girl — including a video of the two sending off Summer’s own message in a bottle out into the ocean.

“It’s the little things that are so amazing as a mom and just make me so happy and proud to be the mother of two beautiful, amazing, incredibly talented, lovely children,” Aguilera, also mom to 7-year-old son Max Liron, told PEOPLE in May.

Wow! Beautiful blue eyes.

Is this the guy she cheated on her husband with?

I love how she is keeping her daughter out of the spotlight this time, more than she did with her son. As much as the public (and I) love celebrity children, this is a time of someone’s life that should be treasured and that you should enjoy for yourself, not for the world to see. Yet, she’s giving a few pics away, which is enough to satisfy the public curiosity 🙂

Summer is a gorgeous little girl. Congratulations to the whole family.

I don’t think it’s about keeping her out the spotlight as much as she’s not out promoting an album or something like she was with Max. She always said she wasn’t going to let the paparazzi stop her from spending tim out with her son and working.

She’s adorable! Her son isn’t very attractive though, poor kid looks like his dad:(

I hope that’s not in California as we are in a drought. That grass and rose garden look mighty perky.

Jane- She didn’t cheat on her husband with anyone (that we know of, anyway). From what I remember, it was a case where she and Matt were friends and she leaned on him as her marriage was falling apart. Then, after she filed for divorce, things turned romantic.

At any rate- Happy birthday, Summer!

She is adorable. Happy birthday!

Max was never put in the spotlight. Paparazzi just chased Christina more back then than they do now. Summer Rain is a gorgeous little girl, just like her mama.
