Yesterday, we mentioned that Lady Gaga had to cancel a few shows because she was suffering from inflammation in her joints. Well now, she has canceled the remainder of her "Born This Way Ball" tour to undergo hip surgery. Her tour operator said her injuries were more serious than she realized. After more tests yesterday, doctors found a tear in her right hip. She needs surgery to repair the problem – and then have strict downtime to recover. Gaga has been on the road for two years, traveling across six continents - and she was scheduled to play another 20 shows here in the US. Live Nation said ticket holders would have their money refunded, starting today.

Monday night on “The Bachelor” - Sean Lowe eliminated Tierra (who has kind of been this season’s villain). Well now, she is engaged to an ex boyfriend! She posted a photo on Instagram last month – where she’s wearing a large diamond ring on her left hand – and fans of the show thought she was trying to fuel rumors that she was the one Sean chose. Then Tierra posted another photo this week - and her brother has confirmed that she IS engaged – but won’t say to who. Apparently, she and her “ex” rekindled their relationship in November immediately after Sean dumped her on The Bachelor. The ex flew out to meet her and they have been together ever since – and got engaged last month.

Kim Kardashian and Kanye West are at the center of a TSA investigation. They had taken a flight from Brazil to JFK – and then needed to head to a connecting flight to L.A. Once they landed in New York, an airline greeter allowed them to bypass a key security checkpoint to get them to their next flight as quickly as possible. This is a major security violation. After Kim and Kanye took their seats on their plane back to L.A., a TSA agent pulled them off the flight ... and made them go through another layer of security. The plane was delayed for about an hour while they were screened by TSA agents. TMZ says a rep for American Airlines says the company is taking responsibility for the incident saying it was a lapse in judgment by one of their employees.
