Lynne Spears and Tish Cyrus chatted over lattes at Starbucks, STAR reports.

The moms for Hollywood's hottest teen stars, the pregnant Jamie Lynn Spears and Miley Cyrus, met for a chat at the coffee joint recently, taking a seat at an outdoor table. Though both ladies were casually attired, their conversation was anything but casual. "Lynn looked upset and was doing the talking," and eyewitness told Star, "while Tish listened intently, nodding her head in agreement."

"The Spears and Cyrus families have become good friends," a source tells Star, "and I wouldn't be surprised if they arranged the chat so that Lynne could share with Tish the lessons she learned as she's tried to deal with care for Britney and Jamie Lynn."
