Things between Kristen Stewart and Robert Pattinson continue to go swimmingly!

The two Twilight lovebirds spent a relaxing Easter Sunday together at Kristen's mom's house, according to Hollywood Life.

"Rob and Kristen celebrated Easter together at her mom’s house in Malibu," reveals a source. "It was low-key, and Kristen’s brothers were there as well."

It sounds like Rob was able to squeeze in a little physical activity on the enjoyable day as well.

“During the day, Rob took the paddle board out," says the insider. "There is a private beach where Jules lives and that’s where Rob always goes paddle boarding. It’s very secluded and private."

Meanwhile, things could not be better for the cute twosome.

"As far as I know, all is perfect in Rob and Kristen’s world," the source spills. "They are really happy to be back together.” 

We're so happy for them! We love how they act like a normal couple, and how they seem to get along so well with each other's families.  

Here's hoping for more smooth waters for Robert and Kristen.
