Pete Wentz and wife Ashlee Simpson named their son Bronx Mowgli in tribute to "The Jungle Book."

The Fall Out Boy rocker - who welcomed his first child with Ashlee into the world last week - has revealed the couple are huge fans of Rudyard Kipling's novel, which tells the story of a young boy called Mowgli who grows up in the jungle and is raised by animals.

Ashlee Simpson and Pete Wentz welcomed their first child together into the world Thursday evening.

The 24-year-old singer - who married Pete, 29, in May - gave birth to 7lb 11oz son Bronx Mowgli late Thursday night at Los Angeles' Cedars-Sinai Medical Center, a representative for the couple has confirmed.

Ashlee Simpson has been trying "different foot massages" to induce labor. The 24-year-old pop star - who is expecting her first child with husband Pete Wentz - is so desperate to give birth she has been testing out a variety of treatments which are said to bring on the labor process.

Ashlee's sister Jessica told U.S. TV talk show host Ellen DeGeneres Monday: "She has been trying different foot massages and stuff. I don't know. I think she's really just jumping around trying everything right now."

Ashlee Simpson reportedly went into labor with her first child over the weekend.

The "Little Miss Obsessive" singer's husband, Fall Out Boy rocker Pete Wentz, was said to have texted his friends on Friday night telling them the happy news that he and Ashlee would soon be welcoming their first child into the world.

P. Diddy reportedly threw a "hissy fit" because he didn't like his all-white themed birthday party.

The rapper - who turned 39 last Tuesday - splashed out on a lavish bash at New York's Mansion nightclub later in the week but insisted the decor was scrapped at the last minute after the all-white room - designed in just 12 hours - failed to meet his expectations.
