It was another news-filled week in the celebrity world, with some stars rekindling their romances while others called theirs off. Plus, one hot starlet is officially one hot mama!

It's official! Robert Pattinson has taken Kristen Stewart back after she was caught cheating on him in July with her "Snow White and the Huntsman" director, 41-year-old Rupert Sanders. The pair was spotted enjoying a cozy dinner at the Chateau Marmont on Saturday, Oct. 13, before reuniting again for a night out at Ye Rustic Inn on Oct. 14. Video footage and photos surfaced of Pattinson and Stewart outside of the Los Feliz, Calif., pub, revealing they left together at 1:30 a.m. Then, their date nights continued into day as they grabbed lunch at a Mexican restaurant in Silverlake on Oct. 15. Robsten is back on!

Speaking of back on, it appears Katy Perry and John Mayer are giving their relationship another go. The couple was spotted celebrating Mayer's birthday in NYC on Oct. 16, heading not only to lunch, but to dinner as well.

Megan Fox and her hubby Brian Austin Green revealed they welcomed their first child together, a baby boy Noah Shannon, on Sept. 27. The first-time mom is over the moon, announcing, "He is healthy, happy, and perfect. We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love."

In much sadder news, "Bachelorette" lovebirds Emily Maynard and Jef Holm have called it quits, along with Russell Crowe and his wife, Danielle Spencer, who have reportedly separated after nine years of marriage.

And how could we forget? Justin Timberlake and Jessica Biel finally tied the knot! The couple announced that they wed in Italy on Oct. 19.
