Sienna Miller's make-up raises eyebrows

The actress proved rather heavy handed in the make-up department, sporting bizarre - and rather distracting - dark eyebrows and dramatic red lipstick during her recent visit to Rome.

Sienna showed off the look as she joined Uma Thurman and Sarah Jessica Parker at a Valentino haute couture show in Rome, conceived as a crescendo to the designer's anniversary extravaganza.

Clearly she is single handedly hoping to revive a trend made famous by Marilyn Monroe and later Brooke Shields and Madonna.

Sienna wore a bold full-length gown - an appropriate tribute to Valentino, who is famed for his lipstick red evening dresses.

The following day, while shooting an advertisement for the designer, she maintained her catepiller eyebrow look.

The star has put on a brave face throughout her Roman holiday - just days earlier she found herself at the centre of controversy.

She has been blamed for the break-up of American rapper P Diddy's long-term relationship with the model Kim Porter, the mother of his three children.

According to reports in the U.S., 36-year-old Miss Porter has moved out of the couple's New York apartment following rumours concerning the nature of Diddy and Miss Miller's friendship.

News of the split came just five days after the rapper and Miss Miller spent much of the evening flirting in the VIP area of London's Paper nightclub after the Princess Diana memorial concert.

As Miss Miller walked into the club, she approached Diddy - real name Sean Combs - and flung her arms around him in a dramatic embrace before appearing to kiss him full on the lips.

They recently also enjoyed a romantic dinner together at the London restaurant Cipriani.

Despite persistent rumours to the contrary, both Miss Miller, and 37-year-old Diddy have denied any romance.
