Obama's budget boss jilts baby mama

Beware Greeks bearing babies!

President Obama's geeky budget guru has a secret love child -- with the Greek shipping heiress he jilted before hooking up with his hot new ABC News fiancée, The Post has learned.

White House Budget Director Peter Orszag's ex, Claire Milonas, gave birth to daughter Tatiana Zoe in New York on Nov. 17, sources said.

The baby was born just six weeks before Orszag and ABC financial correspondent Bianna Golodryga gleefully announced their Dec. 28 engagement on national TV and in the press.

Sources close to Milonas said her family and close friends were stunned by Orszag's boorish behavior.

Milonas' tycoon dad, New York-based shipping magnate Spiros Milonas, 82, hit the roof.

"He had to be calmed down," recalled one close family friend.

Orszag, 41, and Milonas, 39, had been dating for several months when she became pregnant last spring.

"Claire told Peter she was pregnant, and he said he'd marry her -- and then something went wrong," a source close to the situation told The Post.

Orszag met the stunning Golodryga, 31, at the White House correspondents dinner last May and they've been together ever since.

The Post broke the story of the new baby on its Web site yesterday afternoon.

Orszag and Milonas issued a joint statement, saying, "We were in a committed relationship until the spring of 2009. In November, Claire gave birth to a beautiful baby girl.

"Although we are no longer together, we are both thrilled she is happy and healthy, and we would hope that everyone will respect her privacy."

Orszag's friends disputed that Claire was jilted -- and said there weren't hard feelings.

They said Orszag and Milonas parted ways in March, and that Orszag and Golodryga didn't start dating until two months later.

"He made it clear that he wasn't going to marry her, but that he'd help take care of the baby," a source said.

Milonas -- a brainy Yale grad, Harvard MBA and venture capitalist -- and Orszag were featured together in a May 4 New Yorker article. Five days later, he was seated next to Golodryga at the White House correspondents fete.

Instantly smitten, Orszag, who is divorced with two kids, began squiring Golodryga to high-profile social and political events.

Meanwhile, in New York, Milonas registered at upscale baby boutiques and Amazon.com for a "wish list" of self-help books, including one titled "When Things Fall Apart: Heart Advice for Difficult Times."
