- Oracle has hired private investigators to find Hewlett-Packard CEO Leo Apotheker, Reuters reports. The company has subpoenaed Apotheker -- who started his job last Monday -- to testify in a lawsuit claiming $4 billion in damages for software theft. HP has refused to accept the  subpoena, fearing a courtroom attack may undermine his credibility.

-  Wall Street powerhouse KKR is the latest private equity firm to circle Yahoo! for a possible deal, according to the New York Post. KKR's interest is separate from that of other private equity funds. KKR co-founder George Roberts is friendly with Yahoo co-founder and former CEO Jerry Yang, the Post reprots. Several investment firms have looked at taking the Internet company private or helping to finance an acquisition by another Web or media firm. For example, AOL is believed to have talked with private equity firms Silver Lake and Blackstone Group about a Yahoo bid. The PE firms have also looked at News Corp. as a possible partner.

- Kanye West gave a surprise a cappella performance of hit "Gold Digger" on the intercom of a Minneapolis-New York  Delta flight over the weekend. "It was awesome… but I still have no idea how he got into the cockpit," a passenger told Billboard. West also sang a little of "The Good Life."

- Nancy Grace settled a lawsuit  Monday with the parents of Melinda Duckett, who killed herself after being aggressively questioned about her son's disappearance on Grace's CNN show. Grace agreed to establish a $200,000 trust to help fund the search for the child, Trenton, who would have turned six on Monday.

- Following The Hollywood Reporter's exclusive that an ambulance had to be called to an L.A. screening of James Franco's 127 Hours, a Denver viewer opens up about his experience fainting after watching the harrowing amputation scene. "My main concern was not crying in front of my wife’s friends during the emotional parts. To be honest, I wish I would have cried ... It was very embarrassing. I passed out sitting up with my eyes open. My wife tried to talk to me and noticed I was unresponsive, even though my eyes were wide open. She of course freaked. Somebody called 911," the moviegoer told Movieline.
