MANILA - Vice-presidential aspirant Sen. Bongbong Marcos on Tuesday shrugged off the endorsement of host and actress Kris Aquino for his rival, Camarines Sur Rep. Leni Robredo.

Asked if Aquino's endorsement will affect his own campaign, Marcos merely said: "Not really."

The only son and namesake of former President Ferdinand Marcos expressed confidence that Aquino, considered as one of the most influential Filipino celebrity endorsers, will not sway voters away from his strong support base.

"The basis of my support comes from a different perspective," he said.

He added that the endorsement comes as no surprise since the "Multimedia Star" is expected to mimic the endorsement of her brother, President Aquino, for the bets of the Liberal Party.

"That is expected, I'm surprised that it is only now," he said.

Robredo earlier said that Kris Aquino did not only waive her talent fee but also paid for the production and several TV spots for Robredo's political ads.

Robredo's numbers have been steadily climbing in recent surveys and inching closer to those of vice presidential frontrunners Marcos and Sen. Chiz Escudero.

The latest ABS-CBN survey conducted by Pulse Asia shows that Marcos and Escudero were tied at 25%, with Robredo just four points away at 21%.

But while Marcos maintained that Aquino's backing for Robredo will have a minimal effect on his candidacy, he is also wary of a possible surge in the popularity ratings of the administration bet.

Marcos hopes his supporters will not jump to Robredo's side.
