Mom’s little assistant! Newly-single Fergie clasps Axl’s hand as he joins her at work promoting chart-topping new album

She’s racing up the charts with her sophomore album Double Dutchess.

But it was back to mom duty on Monday, as Fergie was pictured clasping the hand of son Axl.

The four-year-old proved her little assistant as the two visited the Elvis Duran show in New York as part of her promotional duties.
