He's ready to take the next step!

Snapchat founder and CEO Evan Spiegel has been ring shopping because he's “ready to take the next step” with Miranda Kerr, whom we spotted yesterday at the Brentwood Country Mart looking absolutely adorable in a polka-dot dress, reports Us Weekly.

The twosome have been going strong since they started dating a year ago and a source tells the mag, “They are both completely smitten and Evan's starting to look at rings.”

This isn't Miranda's first time down the aisle -- she was married to Orlando Bloom, whom she shares 5-year-old son Flynn with, from 2011 to 2013), but she and Evan will still be pulling out all the stops for the wedding.

The pal told the publication that they want to have an “extravagant wedding, in true Evan style." The friend added, "Miranda certainly won’t mind!"

Until Evan pops the question, the 33-year-old and the 26-year-old Snapchat billionaire will be getting cozy in the $12 million Brentwood mansion (formerly owned by Harrison Ford) that they purchased in May. The home is a 7,164-square-foot home with a pool, gym, pool house and guesthouse on a three-quarter–acre lot.

Back in January, the former Victoria’s Secret Angel gushed about her younger but mature man, telling The Edit, she had “the best of both worlds” with him.

“He’s 25, but acts like he’s 50,” explained Kerr. “He’s not out partying. He goes to work in [L.A.'s] Venice [Beach]. He comes home. We don’t go out. We’d rather be at home and have dinner, go to bed early."

Interestingly enough, the Aussie also said that she and her ex have an agreement about bringing their son meeting significant others: “We had to know the person for six months and feel good about them. Evan met Flynn, so, yeah, things are going well. Orlando thinks he’s great. We’re just a modern family now!"
