Editor's note: Pop Tarts erroneously reported that Cruz kisses her sister in the video. While her sister appears in the video, Cruz kisses actress Mia Maestro. Below is the corrected version.

Penelope Cruz may have been nominated for an Oscar last year, but this year, the "Volver" star spices up her younger brother's Eduardo's music video with a lesbian lip-lock.

The video for “Cosas Que Contar” opens with Penelope and her sexy sister Monica sucking lollipops in school-girl inspired outfits before cavorting poolside in racy red swimsuits.

Penelope later shares a smooch with "Alias" actress Mia Maestro.

And while the steamy video is already making media music, could it actually ruin Penelope’s rep as a reputable rather than raunchy star?

“I don’t think it was a wise move for Penelope, as she has always been considered a very classy actress and it wasn’t like she was doing this for a groundbreaking film,” said Adam Weiss, CEO of Weiss PR in New York City (who does not represent Cruz). “But then again, nothing in Hollywood is surprising. People have done worse things and become much more famous as a result.”

But this isn’t the first time that the captivating Cruz sisters have posed together for a project. Spanish fashion giant Mango recently brought 30-year-old Monica on board to design a collection, and she was joined by her “Vanilla Sky” star sister for the promotional pages.

“I don’t think the raunchy video will affect the high-end feel of the MNG fashion line,” a fashion-industry insider told Tarts. “If anything, it will put Monica even more on the map and people will be interested to see her work.”

Vanessa Hudgens’ Mama Supports Nudity

“High School Musical” starlet Vanessa Hudgens is probably better known for those sensationalized nudie snaps than for her sensational singing skills.

And after months of silence, Ness has finally spoken out about the scandal.

“The picture came out while I was on vacation in Australia. Thank God, I wasn't home -- it would have sucked if I was at home,” Vanessa told People magazine. “So I got to be away from L.A. for about a millisecond. But when I came back, it got kind of crazy."

And while most mothers would have been mad (not to mention mortified) if their little girl was splashed across the world in such a way, it seems as though Mrs. Hudgens was full of support.

“I was just open with her, and she was just so cute,” Hudgens said. “She was like, 'Well, everyone can be naked if they want to.’”

Mariah Carey Still Squeezing Into Tight Dresses, Making Diva Demands?

Even though it has been a little while since music star Mariah Carey had a hot hit, the “Heartbreaker” is still reportedly going strong with her signature diva demands.

Pop Tarts has been told that Mariah caused a stir at Tao in Sin City on Monday evening as she cruised into the club just a few minutes before midnight.

“There was some concern that she might not make it down in time for the countdown,” said an insider, referring to the hostess. “Hundreds of people outside were waiting hours to see her and there were mumblings that Mariah would only come when she was totally ready.”

However, once she was rushed down the red carpet through a sea of screamers, Carey settled into the high-profile party, dressed to impress as she squeezed her curves into a tight cream couture dress with gold accents.

But apparently, everything from the trimmings to the tunes were tailored to suit Carey’s oh-so-charming criterion.

We’re told that she and her 30-plus posse (which included “American Idol” judge Randy Jackson) had to be escorted to her private VIP sky box no later than a few minutes after the midnight toast, where the only beverages awaiting them were bottles of Cristal champagne.

Mariah reportedly also requested that the night be spun by none other than her famed friend DJ Suss One, who surprised his pal by debuting her new mid-tempo single with T-Pain titled "Migrate," which certainly got the crowd moving.

But in true Mariah mode, the night was all about the music mogul.

“Organizers made sure that she was showered by sparklers and a large cake to wish her luck in 2008,” an insider told Tarts. “Mariah is still a powerful women, and everybody just wanted to make sure the night was hers.”
