Guitarist Richie Sambora is reportedly caught between two women.

The 54-year-old is said to have secretly been in an on and off relationship with Nikki Lund, his partner in the Nikki Rich fashion line, for the last six years, but is now smitten with musician Orianthi Panagaris after meeting her at a party in Hawaii in December, reports femalefirst.co.uk.

"Richie told people that as soon as he met Ori, something sparked. It's like he's reclaiming his youth with her. He's besotted," said a source.

Sambora is currently touring Europe with Panagaris, who played guitar on late singer Michael Jackson's final tour, and Lund is said to be growing increasingly frustrated that he is neglecting their empire.

The source said: "Nikki's concern is the business. It seems like since he met Ori, Nikki Rich isn't his priority. Basically, Richie's away rocking in Europe with Ori while Nikki's left running the business singlehandedly."

Sambora, who has 17-year-old daughter Ava with ex-wife Heather Locklear, is said to be torn between his professional relationship with Lund and her romance with Panagaris.

His spokesperson said only: "While I do not comment on our clients' personal lives, I can tell you that Richie has an incredibly strong and steadfast work ethic.

"He is very excited about his artistic collaboration with Ori, and is deeply committed to his musical career, fashion company and of course his family."
