Jennifer Aniston and John Mayer were together again for the second stop on his summer tour, which hit St. Louis Thursday night. But rather than acknowledge her presence in the crowd, Mayer teased his audience about interest in his personal life.

“[Fans] send me links from PEOPLE,” he said, marveling at the coverage of his remarks the previous night when he – with Aniston in tow – joked about being the subject of Internet rumors

. “That just tempts me to say things.” The audience at the Verizon Wireless Amphitheater in the St. Louis suburb of Maryland Heights roared its approval, but Mayer would not divulge any intimate details.

Instead, he playfully peppered his nearly two-hour concert with dubious confessions designed to feed those who were curious about his private life: He fears the color green. He weighed 400 pounds when he was 12. He wrote the lyrics to the Kenny Loggins hit “Danger Zone” – at age 9. And he was “33 percent done” with building a time machine.
“When I was a child I would kill small animals and wear their teeth as necklaces,” he deadpanned. “True. Print that. And I’ve always felt deep down that I was born a woman.”

Aniston remained out of sight during the show, but she watched Mayer’s pre-concert soundcheck from the fifth row of the amphitheater, according to radio contest winners who sat a few rows farther back. She wore a slate-colored dress and a cardigan in the damp, late-afternoon air. “She looked like Colbie Caillet,” said a witness, referring to the “Bubbly” singer who served as Mayer’s opening act. “But it was definitely Jen.”

Other fans clearly had Aniston on the brain.

During musical breaks between acts, the twin video screens flanking the stage displayed anonymous notes sent via text message from the crowd. “Team Aniston!” wrote one.

The most brazen of the bunch, preceding Mayer’s own onstage joking: “John, I’m pregnant. – Jen.”

It’s good to have Friends.

Jennifer Aniston met up with BFF Courteney Cox for a humanitarian event at L.A.’s STK restaurant Thursday night – and both brought along the men in their lives.

John Mayer arrived just before 9 p.m., kissing Cox hello and settling next to Aniston (who wore a sleeveless black shirt, grey pants and sky-high strappy sandals). She quickly slipped her arm around him and, a few minutes later, she playfully tousled the singer’s hair.

David Arquette joined them later – after catching the end of the Lakers-Celtics game at the front bar – and the group sat chatting over glasses wine. It was a cozy anniversary celebration for Cox and Arquette, who were married June 12, 1999.

After the STK dinner and event, hosted by Coco de Ville founder Mary Fanaro and sponsored by Kitson, the group headed next door to Coco de Ville, for the OmniPeace.com event honoring Dr. Jeffrey Sachs, co-founder of the anti-poverty organization Millennium Promise.

Good Deeds

Aniston greeted Sachs – famous for his philanthropic work with Angelina Jolie – with a warm hug, and the two sat in intense conversation for 20 minutes. (After Sachs left, Aniston and Mayer discreetly held hands under the table while catching up with Cox and Arquette.)

“[Jen] is absolutely wonderful,” Sachs told PEOPLE later. “She knows that she reaches so many people and is eager to contribute in many ways. It was absolutely fantastic to speak with her.”

As for his other celebrity supporters – Jolie and Aniston’s ex, Brad Pitt – the author of Millennium Promise offered glowing praise.

“They’re so much fun and so committed,” he said. “Angie is just boundless energy, creativity, endlessly so … And Brad is so committed as well with what he’s been doing in New Orleans on environmental issues. It’s phenomenal.”

They may have left Miami, but Jennifer Aniston and John Mayer show no signs of cooling off. The new couple spent a carefree evening in New York Wednesday, complete with neck rubs and PDA.

First, it was dinner at the Waverly Inn, where the couple was joined by three other people in a quiet dinner near the back garden. Mayer’s animated stories kept Aniston laughing as the group sipped white wine and ate a leisurely dinner. At one point, Aniston rubbed Mayer’s neck as the couple spoke quietly to each other.

After dinner, it was on to Hudson Bar and Books, where the group stayed for more than an hour, sipping champagne. Mayer and Aniston weren’t shy about showing their affection for each other – kissing, hugging and posing for photos together. When music started playing, Mayer did a lighthearted – and goofy – little dance.

It was the third city where Mayer and Aniston have spent some quality time together. After getting cozy poolside in Miami on Saturday, they flew to Orlando, where they were spotted kissing backstage at his concert.
