It's true — again? Despite denials of a romance between Brad Pitt and Angelina Jolie, new photographs show the couple on a beach in Africa, according to published reports.

The reports said the photos show Pitt, Jolie and her 3-year-old son Maddox playing in the sand and strolling on the beach. Pitt and Jolie aren't shown being affectionate with each other.

Cindy Guagenti, Pitt's publicist, would not comment on Tuesday on the reports.

Pitt, 41, separated from his wife, Jennifer Aniston, in January. At the time of their breakup, there was speculation in the tabloids of a romance between Pitt and the 29-year-old Jolie, who star in the upcoming film "Mr. and Mrs. Smith."

In its April 18 issue, Us Weekly proclaimed on its cover, "It's True!" over separate photos of Pitt and Jolie. In an article inside, Us quoted employees of a California hotel who claimed they saw the two actors being affectionate.

Guagenti has denied the report, saying "this particular story is completely untrue."

Aniston recently filed for divorce from Pitt after 4 1/2 years of marriage, citing irreconcilable differences. Jolie was previously married to actors Jonny Lee Miller and Billy Bob Thornton.

Over the weekend, Pitt, who is a special ambassador in Nelson Mandela's fight against HIV and AIDS, was in Ethiopia visiting orphans of the AIDS pandemic that is devastating Africa, a spokesman said on Tuesday.

The star of "Troy" and "Fight Club" also visited projects offering AIDS treatment as part of the ONE campaign, which strives to improve trade and debt terms for poor countries and provide lifesaving drugs for people infected with the HIV virus.

His trip was organized by DATA — a Washington-based lobby group co-founded by the rock star Bono.

Pitt was in Ethiopia from Saturday to late Monday
