People: Her love bug? It’s not Herbie

Just days after photos emerged of Lindsay Lohan kissing her deejay gal pal, Samantha Ronson, reports have it that there’s a lot more to their relationship – namely, a wedding.

British tabloid the Daily Star ran photos Tuesday of Lohan sporting a ring on her wedding finger, and reported the 21-year-old actress told a pack of Cannes Film Festival paparazzi she was engaged to the 30-year-old Ronson, who’s openly gay.

Lohan’s publicist, Leslie Sloane, denied the reports, writing in an e-mail:”This is gross. She is not a bad girl. Leave her alone.”

But Us Weekly quoted Lohan’s estranged father, Michael Lohan, as saying his daughter’s relationship with Ronson is “evident to anyone with half a brain.”

Hollywood observers say none of it bodes well for Lohan’s marketability – especially after a string of box-office flops, like last year’s “I Know Who Killed Me.”

“Her image was based on something cute and sweet,” says MSNBC.com Scoop columnist Courtney Hazlett. “The farther she steps away from that, the less well she’s been received in the public and in the industry.”

A bum steer

Ellen DeGeneres and Portia DeRossi, tying the knot at President Bush‘s ranch?

On DeGeneres’ talk show Wednesday, first daughter Jenna Bush Hager was saying how great the ranch was for her May 10 wedding.

“So, can we borrow it for our wedding?” asked DeGeneres, who announced her engagement to DeRossi after the California court ruling allowing same-sex marriages.

“Sure,” Jenna replied.

One major catch: Texas’ constitutional ban on gay marriage.

Speaking of bums …

Country singer Chris Cagle was arrested for misdemeanor domestic assault Wednesday following a drunken fight with his girlfriend.

And a 50 Cent employee faces charges for choking a woman and hitting her with a belt during an argument at the rapper’s mansion.

Officially with child

An African judge on Wednesday approved Madonna‘s adoption of a Malawian boy she met in an orphanage in 2006.

The judge said he was satisfied that the pop star and her husband, British filmmaker Guy Ritchie, “are perfect parents” for David Banda, who will be 3 in November.

Critics accused Madonna of using her celebrity status to circumvent Malawian adoption laws, which she denied.

Cure for what ails her

Good Charlotte frontman Joel Madden says his infant daughter with Nicole Ritchie is already a big music fan.

Harlow, born in early January, grooves to “a lot of Disney stuff and classical,” Madden says. “She likes Good Charlotte. And she likes her granddad (Lionel Richie)’s music. She likes old stuff. She’s a Cure fan.”
