Jay Z's lyric change during the last show of his On the Run Tour suggests Beyoncé is pregnant.

On the couple's last On the Run show in Paris, Jay Z changed the lyrics of his hit song "Beach is Better." Within the lyrics he changed the line "I replace it with another one" to "Pregnant with another one."

With the rapper's sudden lyric change, rumors about the couple transitioned from being about divorce to being about adding a new member to their family.

Prior to Jay Z's lyric change, some have already been thinking that Beyoncé is already pregnant since Jay Z has been fiercely protective of his wife recently.

A source said, "For the last month, Jay has been fiercely protective of her, just like he was when she was expecting Blue Ivy. He's been doing everything he can to ensure that Bey is in a stress-free bubble. He's informed their entire entourage that they need to use relaxed voices, mellow lighting and listen to only soft music, and he's said that all of the food Beyonc eats should be organic.

The source went on to say, "He's really doing his best to make sure that she's as comfortable and healthy as possible."

While Beyoncé's pregnancy is still unconfirmed, some speculate that the rumor might be true, since the "If I Were a Boy" singer had expressed her desire to have another child.

"I think my daughter needs some company. I definitely love being a big sister," Beyoncé said on ABC's 'Good Morning America'.

In a separate interview, Beyoncé described her experience as a mother.

"She's my road dog. She's my homey, my best friend. I feel like I have something that has grounded me so much more. Family has always been important. I've always had my mother and my father and my husband. But it's just ... Life is so much more than ... It's not defined by any of this," she told Vogue magazine.

Meanwhile, as part of the recently concluded On the Run Tour, the couple is releasing a trilogy of videos.

The first clip has already been released, and features a classy French cinema with a classic Western feel.

In addition to the video trilogy, the couple's On the Run Tour concert special premieres on HBO this September 20.
