Singer left holding the baby after Kevin Federline goes on a bender in Las Vegas

Britney Spears is said to be furious after her husband Kevin Federline left her home alone to care for their kids.

The singer only gave birth to her second son, Sutton Pierce, three weeks ago but already Kevin, 27, has left her side to go partying.

He spent the weekend living it up on a lads’ trip to Las Vegas while Britney, 24, stayed home to care for Sutton and 13-month-old Sean Preston.

An onlooker told the New York Post: ‘Kev booked a table at Tao nightclub for both nights where he knocked back Veuve Clicquot champagne and passed around cigars to celebrate his son’s birth. He was surrounded by women and got so into the spirit of things he was seen dancing on tables.’

In an attempt to make things up to his wife, Kevin bought her a pair of diamond earrings. But Britney was said to be less than impressed that he even considered leaving his new son in the first place.

A friend told the Daily Mirror: ‘All Brit wants is for Kevin to be more hands on with the kids. She thought their relationship was back on track.’
