Katie may be devastated, say sources, but it’s hard to top TOM’s island paradise! IN a move that’s sure to break KATIE HOLMES’ heart, TOM CRUISE plans to whisk their beloved daughter SURI off to a spectacu­lar $25 million estate in Hawaii, sources say.

The Hollywood superstar made the decision after vacationing on the tiny island of Lanai, insiders say, and The ENQUIRER has traveled to the tropical paradise to gather behind-the-scenes details of his exotic getaway.

We discovered that Cruise, 50, not only checked out multimillion-dollar properties for him­self and Suri, he also romanced a new beauty and damaged a billionaire buddy’s pricey ride!

“Tom was just blown away by La­nai,” said an insider. “He decided to buy property there over­looking the water and transform it into a fun place that Suri would never want to leave.”

The insider notes that Tom was in­vited to Lanai in mid-January by his close pal David Ellison, who was a producer of the superstar’s last “Mis­sion: Impossible” movie. David’s dad Larry is the billionaire CEO of the software company Oracle and owns 98 percent of the 141-square-mile island, including two ritzy resorts, the Four Seasons at Manele Bay and The Lodge at Koele, where Cruise unwound with pals, said the insider.

“Tom played pool and downed drinks with buddies in the sports bar at the Manele Bay resort,” revealed the source. “And he had a romantic dinner with a young woman at the Nobu restaurant there.”

The “Top Gun” hunk and his mys­tery squeeze also shared drinks at The Lodge at Keole bar and took a ride in a Humvee supplied by Larry Ellison one night, the source said.

“The roads were dark and Tom ended up driving the Hum­mer off the highway,” noted the source.

Fortunately, no one was hurt, and the mishap apparently failed to put a damper on the actor’s enthu­siasm for the island.

Seeking his own slice of paradise, Cruise toured a $4 million three-bedroom spread on exclusive Hulopoe Drive overlooking Manele Bay and the $4.2 million home next door, said the insider.

“Tom’s talking about combining the properties,” divulged the source. “He’d demolish the existing houses and build one big structure. He’s also considering buying four additional $4 million-plus lots – for a grand to­tal of more than $24 million worth of property!

“He wants to make it his own tropi­cal paradise to share with his beloved daughter.”

 would certainly be crushed by her ex-husband’s plan, sources say.

“Lanai is about as far away from Katie’s home in New York as any place in the country,” said the source.

“But as per their custdy agree­ment, Tom has the right to take her anywhere if Katie agrees. So Suri could stay with him in Hawaii for weeks or even months at a time.

“Katie would be devastated, but it would be hard for her to top Tom’s private island paradise.”
