One season and she's out: Former tennis star Anna Kournikova won't be returning to "The Biggest Loser."

Kournikova was one of two trainers brought aboard to join Bob Harper after Jillian Michaels left the show last season.

Known for her glamorous good looks, she struck some viewers as a curious choice.

But Kournikova said she had plenty in common with the obese contestants on NBC's reality weight-loss show, including that years in the media spotlight left her struggling with feelings of inadequacy and insecurity about her looks.

However, her tenure got off to a rocky start. This season's theme is "Battle for the Ages," pitting youth against oldsters. Kournikova ended up with the senior set, and they have struggled, losing several weigh-ins and challenges.

Moreover, she created conflict with several of the players -- and made no friends with viewers -- with a less-than-sympathetic demeanor.

Good-natured Joe, for example, bristled when Kournikova essentially told him to man up and get over some of his issues.

Each week, during media conference calls with the eliminated players, contestants sang Kournikova's praises -- including Joe, who was eliminated last week but said he credited Kournikova as being key to his weight-loss success.

But the Hollywood Reporter, which broke the news about Kournikova's departure, hinted that Kournikova was clashing with folks on and off camera.

Diddy to honor friend Heavy D

Rap mogul Diddy and the Rev. Al Sharpton will speak at late rapper Heavy D's funeral on Friday, and BET plans a tribute for him at the Soul Train Awards.

Diddy said in a statement that he was "heartbroken by the passing of my dear friend."

"He was a wonderful human being, who inspired and paved the way for a Hip Hop generation," the statement said. "We were like brothers. I will miss him more than words can express."

A private funeral for the rap legend will be held at Grace Baptist Church in Mount Vernon, just north of New York City.

Heavy D, born Dwight Arrington Myers, died at a Los Angeles hospital last week after collapsing outside his home. He was 44.

The rapper was the frontman of Heavy D and the Boyz, which had hits with "Now That We Found Love," "Who's the Man" and "Somebody for Me." He was one of the genre's top stars in the late 1980s and early 1990s.

BET also announced Monday that the Soul Train Music Awards in Atlanta will pay tribute to Heavy D, with Kurtis Blow, Naughty by Nature, Big Daddy Kane, Doug E. Fresh, DJ Eddie F, Whodini and Daddy-O of Stetsasonic participating.
