Lauren Conrad is apparently on the fast track to marriage.

The 26-year-old fashion designer has been dating law student boyfriend William Tell for four months now.

And friends tell Us Weekly that as she openly smooched her beau in a Los Angeles coffee shop recently, she was happy that they didn't need to keep their romance a secret any longer.

"She was relieved when news that they're dating came out," a source told the publication. "They don't have to hide."

Lauren apparently met William during a double date on Valentine's Day but they are rarely photographed together.

"Lauren is incredibly happy," the insider added. "I think they'll eventually get married."

William's ex-girlfriend, Bachelor runner-up Sadie Murray, said that the former Something Corporate musician is perfect for Lauren because that he "doesn't date just to date. He's either deeply in love or he's on to the next thing."
