CHRISTINA AGUILERA - AGUILERA BEGGED HOLLY VALANCE FOR ACTING LESSONS

Pop princess CHRISTINA AGUILERA has begged Australian actress-turned-singer HOLLY VALANCE to teach her how to act, despite rowing with her at a casting earlier this year (04).

The DIRRTY singer first met Valance when they competed for lead roles in a remake of '60s classic VALLEY OF THE DOLLS and reportedly ended up shouting at her for wearing a similar outfit.

But Valance refused to let the insult upset her and Aguilera is reportedly astonished by her confidence.

One insider tells Britain's DAILY STAR newspaper, "Christina told Holly that she thought she had deliberately worn a raunchy outfit to show her up.

"But Holly just laughed and took it on the chin. The next thing was, Christina laughed too and they just hit it off. Christina was bowled over by Holly's presence on camera."

The pair have kept in touch since their initial meeting and Aguilera has sought advice on up-and-coming movie projects.

An insider reveals, "They've spent days on end together larking around. They are actually quite similar and have the same interests."
