LOS ANGELES

American actor Kate Mara, who announced her pregnancy this year in January, welcomed her first child and guess what, it's a baby girl! The actor and Jamie Bell welcomed their first child together earlier this month, reports E-News.

Giving a glimpse about their newborn, the actor posted a picture showing the tiny feet of the baby on Instagram. "We had a baby a couple of weeks ago... Here are her feet." Jack Bell, who Jamie shares with his ex-wife Evan Rachel Wood, was the first person to meet the little bundle of joy.

A few weeks ago, the famous couple hosted a festive baby shower at their Los Angeles home. The 36-year-old's sister Rooney Mara and her beau, Joaquin Phoenix, attended the pink-themed soiree, which was decorated with beautiful arrangements of wildflowers and roses. Multiple outlets reported that the lucky guests showered the first-time mom with presents wrapped in pink paper.

While the mom-to-be grabbed eyeballs at the shower, all of her attention was devoted to Jamie's son, Jack. A source told Us Weekly, "[She] spent a lot of time playing with Jamie's son in the yard."
