Call me an old softie, but I think one of the cutest new couples to emerge from last year is Russell Brand and Katy Perry. True, I didn’t think it would last, and true, I still don’t think it will last. But while it’s still happening, I enjoy them together. They’re kind of adorable together. And now we get to enjoy it even more – Us Weekly is reporting that the two are engaged! Of course, this hasn’t been confirmed by either’s rep, but rather “sources” tell Us Weekly that Russell popped the question while they were on vacation in India. That’s so… sweet. I’m being serious!

He kissed a girl, and she liked it: Katy Perry and Russell Brand are engaged, sources confirm exclusively to UsMagazine.com.

The wacky pair — who’ve been dating since September 2009 — became betrothed five days ago while on holiday in Jaipur, India. A pal says that Brand, 34, proposed with a ring, and that Perry, 25, happily accepted.

On Twitter Dec. 29, the pop singer shared a sweet snapshot of her and the British comedian in front of India’s famed Taj Mahal. “He built this for me,” she wrote beneath the photo.

The exotic trip, a Perry insider tells Us, “was his Christmas gift. She told him how much she loved Indian culture while they were eating curry in England, so he surprised her.”

On New Year’s Day, she shared another tourist photo: her hand being painted with a traditional Henna tattoo. (“Isn’t it lovely?” she wrote.) The day before, she perhaps hinted at spontaneous decisions to come later that week: “In India, the motto…you gotta go with the flow…”

At November’s MTV Europe Music Awards, Perry paid tribute to Brand via her on-stage underpants, emblazoned with his nickname, “Rusty.”

Of their romance, a friend tells Us that Perry has “never connected with anybody like this.” As for Brand, the Forgetting Sarah Marshall star “is super into her. She says he makes her laugh like nobody else in the world,” an insider says.

If it’s true, then congratulations to them. It sounds like the kind of thing Russell would do on a whim, which is why I tend to believe it. Now, is Russell ready to hang up his orgy pants to become a one-woman man? Is Katy woman enough for such a famous “swordsman” (as the Brits say)? Meh. I think Katy genuinely has a hold on Russell and he’s trying to change for her. Will it last? Probably not. But I’ll bet they have a lot of fun until then.
