Kevin Federline cares for kids

Mar 6, 2007, 12:30 GMT

Kevin Federline took his two children to Las Vegas for the weekend.

The 28-year-old - who has custody of sons 18-month-old Sean Preston and six-month-old Jayden James while estranged wife Britney Spears is in rehab - travelled to Las Vegas for an appearance at the Mirage Hotel and Casino lounge Revolution.

A source told People magazine: "Kevin was really low key. You could definitely tell he was on his best behaviour. He was having a good time, but wasn't the wild, crazy Kevin who used to come to Vegas."

The aspiring rapper arrived on Saturday (03.03.07) with the boys, a nanny, his mother, brother and two bodyguards.

He dined with family and friends at the hotel restaurant Japonais.

The source added: "He was late for dinner because he wanted to tuck his kids into bed."

Meanwhile, Britney is said to be responding well to treatment in Malibu's Promises centre and has been enjoying some online retail therapy.

Sources reveal she has spent over $3,000 on clothes, including several fedora hats, Daisy Duke shorts, sunglasses and a designer dress.

A source told gossip website TMZ: "Britney emailed her cousin, Ali, a list of all the things she wanted from a website."

She also asked for this season's 'must-have' dress, a red and gold bamboo cap-ribbed dress in a size small and one of their Eternity shawls in light blue.
