LOS ANGELES: Justin Timberlake and Jessica Biel are said to be

going through a rocky patch, but those close to them have denied claims they have split.

A source said, “Things have been a bit up in the air recently. They have been spending more time apart — more time with each of their friends, and they have been re-evaluating their relationship.”

Last month, 27-year-old Jessica attended the Los Angeles wrap party for new movie Valentine’s Day alone. Justin, 28, was spotted partying with pals in West Hollywood days later.

Another source claimed, “They are together. They are not breaking up. Any time they spend time apart it’s because they are working.”

Recent reports have claimed the pair split up to a month ago, but are not ready to go public with the news.

It has also been suggested Justin has grown close to singer Rihanna, 21, while they have been working on new music together.

The star’s close friendship reportedly put increased strain on his relationship with Jessica.
