Steven Tyler engaged to girlfriend Erin Brady?

Aerosmith singer Steven Tyler is apparently set to walk down the aisle again, and lucky lady No. 3 is Erin Brady, the hot-tempered, sometimes-redhead who has been Tyler’s significant other for most of the past decade. The couple – he’s 63, she’s much younger – spent Christmas in Maui, and Brady was spied sporting an enormous diamond ring. If TMZ can be believed – and it usually can — Tyler’s family, including children Liv, Mia, Chelsea and Taj, are none too happy that dad is getting hitched again. They think Brady, a 38-year-old former Live Nation tour accountant, is “mean” and they’re upset that Tyler didn’t alert them before popping the question. It’s true that Brady has displayed some not-so-sweet emotion in the past. Four years ago she got into a knock-down-drag-out fight with a female Aerosmith fan at Pangaea nightclub in Hollywood, Fla. According to witnesses, Brady exchanged words with the woman and then the pair got into a full-on brawl — slapping, punching, and pulling hair. Tyler has been married twice before – to David Johansen’s ex-wife Cyrinda Foxe in 1978 and, 10 years later, to Teresa Barrick. Will the third time be the charm? His own memoir would suggest otherwise. In “Does the Noise In My Head Bother You?” the “American Idol” judge says it’s tough to teach an old dog – and he’s definitely a dog – a new trick. “If you ever meet guys who have had three, four wives, you know they keep getting married to the same woman over and over,” Tyler writes. “They pick a new woman who’s just like the old one every time.” In the book, Tyler calls Brady a “tough chick” and reveals that the two were in rehab together at California’s Las Encinas Hospital in 2007 — one of eight times Tyler was in rehab. Talking recently to Oprah Winfrey, Tyler said he was “ashamed” of his past womanizing. “I don’t want to hurt anybody again. For all the divorces I’ve had, I’ve hurt those girls deeply. There was some behavior that I’m ashamed of and I shouldn’t have done,” Tyler said. For the record, Tyler’s rep had no comment about any of this.
