Wow… Chris Pratt just posted a VERY mushy tribute to his new girlfriend

If there was any doubt that Chris Pratt had a new woman in his life, he's pretty much just dispelled it.

The star has publicly confirmed his romance with Katherine Schwarzenegger on Instagram. Posting a collage of her to wish her a happy birthday, he said that he was "thrilled" that God had brought them together. "Happy Birthday Chief!," he wrote. "Your smile lights up the room. I’ve cherished our time together. Thrilled God put you in my life. Thankful for the laughs, kisses, talks, hikes, love and care." The couple have reportedly been together for six months. They were papped kissing on a family day out with Chris's son Jack, from his relationship with Anna Faris, during the summer.

Chris may be one of the biggest actors in the world, but Katherine comes from pretty famous stock herself. Her father is Arnie and her mum is American journalist Maria Shriver. A source close to the family has said that they're all super keen on Chris. “Everyone has their fingers crossed that this is going to work out long term. They think Chris is an amazing guy and a great catch. “They are really perfect together and have similar goals and values. They have gotten serious quickly!”
