Katie Holmes and Suri CruiseSuri Cruise will turn 5 on April 18, and mom Katie Holmes talked excitedly about plans for the big day.

'The Kennedys' star shared some of the details with Ryan Seacrest on his KIIS-FM radio show, revealing plans that are surprisingly low-key for Suri, who is known to wear designer clothes and heels.

E! Online reports Holmes saying, "She's [Suri] turning 5 in about two weeks. She wants a piñata and her girlfriends to come over [and go] swimming. We're gonna make a cake together."

Holmes continued, "This is my favorite day of the year. So we're gonna have a little tea party, and I like to girl it up."
