Grimes, 23, and Beech, 24, began dating in the spring of 2012. The two are planning to tie the knot in England sometime next year, according to one insider.
"Josh couldn't see himself being with anyone else so he asked her and she is over the moon about it," a pal tells Us of their engagement. "They fell for each other hard and since they've met, they talk non-stop. If they're not around each other, they're texting, calling and tweeting back and forth all the time."
Grimes is currently shooting the fifth season of 90210; the CW hit recently aired its 100th episode, which featured guest stars Carmen Electra, Taio Cruz and Denise Richards. In addition to modeling for brands like Burberry, Just Cavalli and Levi's 501 Jeans, Beech also designs a line of T-shirts with his friend, Sam Kent.
