ROCKER ROD STEWART should make the most of his summer break. After all it won`t be long before the Bizarre Lord is back to a life of sleepless nights and changing nappies. Here`s Rod taking time out in Malibu with wife PENNY LANCASTER - just days after announcing the photographer is expecting his 8TH child. The pair - who have a son Alastair, four - discovered the nappy news as they celebrated their third wedding anniversary in Italy in June. The baby is due shortly before Penny turns 40 in March. Rod`s ex Faces bandmate RONNIE WOOD sent his congratulations to the singer at the band`s first reunion concert in London last night. Simply Red singer MICK HUCKNALL replaced Rod who chose not to rejoin the band at last night`s gig. He said: "Good luck to him, he`s a great dad. "We do miss Rod but having Mick here is just unbelievable because it`s one of those situations that you probably at first think wouldn`t work but it`s magic." Rod has six other children - KIMBERLY, 30, and SEAN, 29, by first wife ALANA HAMILTON; RUBY, 23, by model KELLY EMBERG; and RENEE, 18, and LIAM, 15, by second wife RACHEL HUNTER. His first daughter SARAH, now 46, was born when he was 19 and was given up for adoption.
