Scarlett Johansson's privacy about her love life may give fans and the media headaches, but it only impresses another Hollywood starlet.

OK! has learned that Jessica Biel has been taking dating advice from ScarJo, who was once romantically linked to none other than Jess’ boyfriend Justin Timberlake!

“Jessica is adamant that she and Justin are happy and there are no problems,” a pal of Jessica tells OK!. “But she wanted to get a female perspective on the best way to handle all the rumors about him with other girls.”

So what did Scarlett, who's been quietly dating Ryan Reynolds, tell Jessica? Ignore the tabloids and focus on the relationship!

“Jessica was pretty open to Scarlett’s opinion and appreciated her honesty,” the pal confirms. “She had an idea that when she got back from filming [Easy Virtue] she should teach Scarlett to golf so they could double-date with Justin and Ryan.”
