Miley Cyrus looked quite conservative during a hike with boyfriend Patrick Schwarzenegger amid cold weather Friday. The couple even bumped into Nicole Richie who was also walking her dog at Runyon Canyon.

According to Daily Mail, Miley Cyrus and boyfriend Patrick Schwarzenegger were resting on top of the slope when Nicole Richie came puffing over.

"It appeared they greeted each other and chatted for a bit before going their separate ways," it said.

The cold weather prompted Miley Cyrus, who has been wearing racy outfits and posing topless of late, "was dressed in a much more conservative and subdued manner than usual, wearing a blue sweatshirt, black leggings, and sneakers."

Meanwhile, Madonna defended Miley Cyrus, who just appeared a nude photoshoot with V Magazine.

During a guesting at Jonathan Ross show in London, the pop icon said, "We live in a different time," she told Ross. "Image is a big part of our work. We are exploring our sexuality."

"I love Miley [Cyrus], Gaga, all these guys," she said.

For the V Magazine photoshoot, Miley Cyrus continues her "Diary of a Dirty Hippie" and her breasts again take center stage.

"The photos were snapped by her pal Cheyne Thomas at Art Basel in Miami last December, but noticeably absent are her pasties. Miley has long been a #FreeTheNipple supporter, so we shouldn't be that surprised," reported X17.

In one of the photos, she's wearing nothing but a tinsel wig while counting dollars and smoking a cigarette.

According to Hollywood Life, Miley Cyrus and Patrick Schwarzenegger are a "kinky couple."

"She just bought a sex swing and they're loving it so much. She's been telling everyone how great it is. She says she's giving one to all her friends for their birthdays this year because she thinks everyone should have one," the source said.
