Is Brody Jenner getting ready to put a ring on Avril Lavigne's finger?

"They're almost a year together," Jenner's mom Linda Thompson told us last night at the Global Action Forum awards gala in Beverly Hills. "She's an amazing young woman and I feel really fortunate that she's in our lives."

So have the couple started planning a walk down the aisle?

"Not yet," Thompson said. "I mean they're very young. They both have their careers to concentrate on."

But that doesn't mean Brody's mama doesn't think they'll one day tie the knot!

When asked if she thinks they'll be together forever, Thompson gushed, "I actually do yeah."

"You never know what will happen but they are well suited for each other," she said. "She's such a lovely person and surprisingly, she's a real home body. She loves to cook and she's really grounded and very familial. She's into close-knit family time. I really respect her."

What makes Jenner and the punk-pop singer click so well?

"They have the same sense of humor," Thompson said. "They both love to laugh and have fun. They both have a little streak of irreverence which is pretty delightful and a lot of fun to be with."
