Jessica Biel just set those Justin Timberlake rumors straight with new Instagram post

Jessica Biel has just set the rumors about a rift between her and her husband Justin Timberlake straight with a new Instagram post.

The couple's relationship was plunged into a public crisis last year when The Sun published pictures of Timberlake holding hands with his Palmer co-star Alisha Wainwright in November.

This sparked rumors of an affair, which Timberlake issued a public apology denying.

Wendy Williams speculated that Timberlake was forced to apologize by Biel:

Now, in celebration of her 38th birthday, Biel has posted pictures of herself and her husband on Instagram, showing that they are very much a couple - and seemingly a happy one.

"Celebrating my birthday in style... and by that I mean, in pajamas," she wrote. "I made Justin PROMISE not to sing Happy Birthday to me, so he improvised. Sorry, you can't hear it, but I'm still laughing."

Timberlake, 39, also took to the social media platform to wish his wife a happy birthday.

"Happy Birthday to the LOVE of my life... A new adventure every day and a treasure to me. I can't wait to share many more of these with you," he wrote. "Thanks for putting up with me when I smell funky after a round of golf or, when I smell funky in general. You are the mostest of the mostest, my love! I adore you."

However, despite such a positive post, Timberlake was slammed in the comments section today from people who claimed that if Biel was the love of his life, he would have never held another woman's hand while married to her.

A similar incident also took place in December when the singer left a flirty comment under an Instagram video of Biel.

So, while it's clear that it will take a while for the couple to change public opinion about the status of their relationship, it's definitely something that they are trying to do on social media.
