Britney Spears and her ex-husband KEVIN FEDERLINE both celebrated Father's Day separately in Las Vegas this weekend (15Jun08).
The couple - whose divorced was finalised in July last year (07) - was both photographed in Sin City, but carefully managed to avoid each other.
Spears, 26, was seen sipping water at the Palms Place hotel, while Federline picked up his Father of the Year award at Prive Las Vegas.
It is the second time Federline has been handed the honour: he was previously given the title by Details magazine last November (07).
The former couple left their two children Sean Preston, two and Jayden James, one, at home for the weekend.
