Sir Paul McCartney has personally laid flowers for Whitney Houston. The Beatles legend was in Los Angeles when the 48-year-old singer was found dead at the city's Beverly Hilton hotel on Saturday and wanted to leave a personal tribute to the "I Will Always Love You" star.

He was seen with wife Nancy Shevell at the makeshift memorial created outside the hotel yesterday dressed casually, and left a bouquet of yellow roses at the scene. When fans tried to congratulate Paul on his performance at the Grammy Awards the previous night, he shrugged it off.

"This is about Whitney, not me," TMZ reports that he insisted.

Following Whitney's passing, a host of stars have paid tribute to the singer. Mariah Carey tweeted, "Heartbroken and in tears over the shocking death of my friend, the incomparable Ms. Whitney Houston."

"Mine is only one of the millions of hearts broken over the death of Whitney Houston.I will always be grateful and in awe of the wonderful performance she did on my song and I can truly say from the bottom of my heart, 'Whitney, I will always love you. You will be missed,' said Dolly Parton - who wrote Whitney's hit "I Will Always Love You."

"I just can't talk about it now. It's so stunning and unbelievable," said Whitney's godmother Aretha Franklin.
