Just a few months after losing her beloved 14-year-old poodle Pearl, she was surprised with a new dog a few days before the big holiday.
"Most amazing surprise early Christmas gift #penny #inlove," she Tweeted on Friday, with a photo of her new fluffy black and white pup named Penelope, or Penny for short.
In October, the former iCarly star told PEOPLE how much she missed Pearl, who had been a fixture in her life for many years.
"She was a part of our family, and because I was an only child, she was a really big part of my life," Cosgrove said. "Every time I look back on a memory, she was there."
Now the actress, who is a freshman at the University of Southern California, will be making new memories with Penelope. In fact, it seems like she's already started. On Dec. 22 and again on Dec. 23, she Tweeted more photos of her new pooch.
