Britney Spears finally appeared Thursday for a deposition in Los Angeles in her child-custody battle with Kevin Federline, her ex-husband's lawyer said.

Spears was deposed for just 14 minutes, attorney Mark Vincent Kaplan told reporters after the 26-year-old singer left.

Paparazzi sprinted after Spears, who was wearing a hot pink dress and sunglasses, as she drove away from the Century City office tower in a white Mercedes-Benz. Security guards dashed across the driveway to keep photographers on the sidewalk.

Spears called in sick for a Dec. 12 court-ordered deposition, but was photographed that day driving with a friend. She also didn't show up for a session Wednesday, Kaplan said.

Spears' attorneys from the firm Trope and Trope filed a court motion Wednesday asking to be relieved due to a "breakdown" in communication with their client.

Kaplan said Spears' attorneys were present for what became a very abbreviated session.

"The deposition proceeding did go forward today. It was scheduled for 9:45 to 11:45," Kaplan said. "However, it wasn't able to commence until 11:32."

"You can imagine in 14 minutes there's not a lot of time to develop questions," he said.

Kaplan said another deposition will be scheduled.

Spears' representatives didn't speak to reporters outside the office building.

Spears and Federline, 29, have been wrangling over custody of their sons, 2-year-old Sean Preston and 1-year-old Jayden James.

Federline has temporary custody of their two sons because Spears, who has limited visitation rights, has defied court orders. The two were married in October 2004 and divorced in July.
